Problem

When hovering screen sharing, a user can see the "Zoom in" cursor. It is supposed to mean that click on the screen sharing zooms it in. While in fact it only zooms on double click.

At the same time, double-click on a video often goes "fullscreen", which is especially actual for screen sharing.

Proposal

• Zoom in with a single click or explicit controls
• Use double click to switch to Talk Fullscreen mode

Start by locating the screen-sharing and video interaction entry points in the frontend. Verify the current click and double-click behavior, then confirm that a single click or explicit control zooms screen sharing and a double click switches to Talk Fullscreen mode.
