Perhaps we add a subsection for each remote end step. Right now it's unclear what you're defining in each case unless you look at the POST closely. It could be in a title.

I still don't understand how the behavior is limited in terms of interaction to make sure it cannot be exploited. Or is that a question for later?

I'm not sure I understand the concern. Webdriver APIs are not exposed to the web (and also not enabled by default). See, for example, https://chromedriver.chromium.org/security-considerations

There are lots of ways webdriver can be exploited if that weren't the case since the APIs are very powerful.

This is only meant to be used by local automation/testing tools

## Cancel dialog ## {#webdriver-canceldialog}

<figure id="table-webdriver-canceldialog" class="table">

<thead>
<tr>
<th>HTTP Method</th>
<th>URI Template</th>
</tr>
</thead>
<tbody>
<tr>
<td>POST</td>
<td>`/session/{session id}/fedcm/canceldialog`</td>

</figure>

The [=remote end steps=] are:

1. If no FedCM dialog is currently open, return a [=error|WebDriver error=] with
[=error code=] [=no such alert=].

1. Close the dialog and continue the [=create an IdentityCredential=] algorithm
as if the user had canceled the dialog without choosing an account.

1. Return [=success=] with data `null`.

## Select account ## {#webdriver-selectaccount}

</figure>

The [=remote end steps=] are:

1. If |parameters| is not a JSON [[ECMASCRIPT#sec-json-object|Object]], return a
[=error|WebDriver error=] with [=error code=] [=invalid argument=].

1. If no FedCM dialog is currently open, return a [=error|WebDriver error=] with
[=error code=] [=no such alert=].

1. Let |accountIndex| be the result of [=getting a property=] named `"accountIndex"`
from |parameters|.

1. If |accountIndex| is {{undefined}} or is less than 0 or greater than or
equal to the number of accounts that the user can choose from in the
current flow, return a [=error|WebDriver error=] with [=error code=]
[=invalid argument=].

1. Close the dialog and continue the [=create an IdentityCredential=] algorithm
as if the user had selected the account indicated by |accountIndex| and
[=request permission to sign-up|granted permission to sign-up=], if applicable.

1. Return [=success=] with data `null`.

The [=remote end steps=] are:

1. If no FedCM dialog is currently open, return a [=error|WebDriver error=] with

from in the current flow.

Note: This command lets automation verify that the
[context api](https://github.com/fedidcg/FedCM/blob/main/proposals/context-api.md)
was applied properly

The [=remote end steps=] are:

1. If no FedCM dialog is currently open, return a [=error|WebDriver error=] with
[=error code=] [=no such alert=].

1. Let |data| be a dictionary with an object with properties as follows:
1. `title` set to the title of the open dialog
1. `subtitle` set to the subtitle of the open dialog, if there is one

1. Return [=success=] with data |data|.

The [=remote end steps=] are:

1. If no FedCM dialog is currently open, return a [=error|WebDriver error=] with
[=error code=] [=no such alert=].

1. Let |type| be a string that is "`AutoReauthn`" if the user is being [=auto-reauthenticated=],
or "`AccountChooser`" otherwise.

1. Return [=success=] with data |type|.

The [=remote end steps=] are:

1. If |parameters| is not a JSON [[ECMASCRIPT#sec-json-object|Object]], return a
[=error|WebDriver error=] with [=error code=] [=invalid argument=].

1. Let |enabled| be the result of [=getting a property=] named `"enabled"` from
|parameters|.

1. If |enabled| is {{undefined}} or is not a boolean, return a [=error|WebDriver error=]
with [=error code=] [=invalid argument=].

1. If |enabled| is false, disables the [=promise rejection delay=]; otherwise,
re-enables it.

1. Return [=success=] with data `null`.

## Reset cooldown ## {#webdriver-resetcooldown}

<thead>
<tr>
<th>HTTP Method</th>
<th>URI Template</th>
</tr>

<tbody>
<tr>
<td>POST</td>
<td>`/session/{session id}/fedcm/resetcooldown`</td>
</tr>
</tbody>
</table>
</figure>

The [=remote end steps=] are:

1. If the user agent uses a cooldown delay, which disables the API for an
amount of time after the user dismissed the dialog, then this command
resets that cooldown such that the next FedCM call can succeed again.

1. Return [=success=] with data `null`.
