I’m far from an expert on this but intents are (as I have understood it) kind of like you tell the phone to do something or an app can say “I did this” and everyone else can listen and say “Ok”…
If the app has an intent for this button to be pressed then it should be possible to “push” the button from HA.
The issue is to find what the command is. There is a listener in the app that can help you or you can google for “intents [app name]”.
If you get it to work, don’t forget to share your finding/work Android Intents - Sending & Receiving List (Starting Activities too!)
