Separate "application IDs" for pympress content and pympress presenter

[pank]

Is your feature request related to a problem? Please describe.
I was trying to give a presentation via Cisco WebEx with Pympress on Windows. However, WebEx only allows sharing both of the Pympress windows, i.e. content and presenter. This isn't great as I want to be able to see my notes in the Presenter mode so I only want to actually share Content.

Describe the solution you'd like
It would be good if Pympress Content could somehow be separated further from Pympress Presenters to trick buggy software like WebEx to not group them together.

I have no idea how one would go about doing this in practical terms so this is a bit of a long shot...

Additional context
Since it's a bug with WebEx also feel free to disregard this request.

I think we have the same application id but different window ids for Gtk − though I don’t know how that translates on Windows, nor how WebEx figures out application ids. Worth looking into at least, to figure out what can be done.

Unfortunately it’s somewhat unclear to me at the moment how webex identifies applications vs windows. I think at the moment the best would be to have the content window on a different screen and share that.

I managed to fake an additional screen using the method described in this superuser answer, un-fullscreen the pympress content window, slide it offscreen on the side where the fake screen is, and press f to make it fullscreen again. This window is then detected and shareable in webex.
