I checked out the Take Photo action and looks like it only allows using either the primary front or the primary rear camera, although nowadays many phones come with multiple cameras (for instance my current galaxy note 10+ which has both a wide and a narrow camera).
Selecting one of the extra cameras isn't that hard in code: the Camera2 API enumerates all cameras, even the extra ones.
I'd like to request this feature so I can use any camera on the Take Photo action.
