Hi, and thanks for your first contribution to Ory Kratos!

I don't think you have found the correct place to add a new parameter yet. You edited the generated Go client (which we check in to do internal testing), but you need to actually add the parameter to the handler.

This is the handler for list identities: https://github.com/ory/kratos/blob/master/identity/handler.go#L185

Also please make sure to add tests and a docs PR (in general, make sure to tick all check boxes in the PR template). Thanks!
