Share my screen on a tablet device with nextcloud talk

Hello all,

I have a nextcloud server running the Nextcloud Hub II (23.0.2) and nextcloud talk application installed and updated to the latest version. I have used it on my PC to great success and love it.

Today I tried to use it from my Samsung S7 Tablet so I could share the samsung notes and draw during the talk. Surprise: I couldn’t see the share my screen buton!

Is there no such feature for the mobile version? Or do I have to allow something for it?
