Linux client - fix keyboard shortcuts

Is your feature request related to a problem? Please describe.
The Linux Zoom client makes it hard to navigate the gallery view (KDE, Wayland, others too) - the “blue arrows” only appear when the window is resizing.

If the keyboard shortcuts (e.g. “show next 25 participants”) functioned, that would be a workaround, but they dont.

Describe the solution you’d like
Fix keyboard shortcuts to be more like the Windows/iOS clients.

Describe alternatives you’ve considered
Fixing the prev/next arrows in the gallery view would be just as good…

Additional context
I’m a dev, and I’m regularly in Zoom meetings with >50 particpants, so I’m well positioned to help.
