Use my apps in a flow

I have managed to create my first app, and after the CLI command Homey App Install, it is visible in the list of apps in my homey web interface.

Now I want to use the app in a flow, in a Then part.

But I cannot see the app in my advanced flow creation windows.

I did modify my .homeycompose\app.json and added this part.

That should do the trick, according to AI, but it does not.

So what steps do I need to take to make my app visible in a flow card ?

Thanks for the real Human Intelligence.

How about start with the Fine Manual? Flow | Homey Apps SDK

That doesn’t work, you should create files for each action in .homeycompose/flow/actions/(id).json. And then you should remove the ID parameter from the JSON file
