How do I launch the Open Camera app to take a picture without user interaction?

Question

I am trying to launch the Open Camera Android app to take a picture without user interaction for meter reading logging purposes. Plenty of examples on the web to do this using Android intents with user interaction (i.e. they have to press a button) but none I can find how to do this without. Could modify the Open Camera source to do what I want but that seems like overkill if I could just use an existing application and launch it from mine.

That is because there is no option for that.

Or you could use an existing camera library (CameraX, FotoApparat, CameraKit-Android, etc.) and take the picture directly from your app.
