Charge Amps Aura missing functionality

[Miggle007]

I am gladly using this integration and I am able to do the following:

• Read the current power usage per connector (the Aura has two connectors)
• View the actual status per connector (available, charging, ..)
• Switch the connector on or off
• Dim the light
• Read the total consumed energy

However, I am mainly missing the thing that I want to automate on: Set the current per connector. When taking a look at the REST API documentation this is available. When digging in to this custom component it seems to be built in to this integration.

Does anyone recognize this?
Does this also has to do with the CAPI > OCPP?
