Pressing a button through automation

Configuration

I have the EV Smart Charge add-on installed together with Volkswagen Connect.

I nee to create an automation, that can stop charging on the EV, if the EV Smart charge indicates that it isn’t the right time to start charging…

From the VW integration I have:

But when creating an automation to press A button, there is no GUI option to pick the button… only input like:

action: button.press
metadata: {}
data: {}

How do I specify the button from the VW integration to press ?

action: button.press
metadata: {}

target:
  entity_id: button.id_4_pro_stop_charging
