Zoom unable to share screen

Currently running the most recent flatpak Zoom on fedora 38 [us.zoom.Zoom;]
The Zoom download center offers Version 5.14.7 (2928)
The ‘always a little behind’ thing rarely causes a problem; but right now prevents screen sharing and causes some system instability.
Zoom support is uninterested, simply pointing out that their RPM package is “up to date”. Can anyone offer a solution that does not involve RPM’s? Keeping that up to date was a huge pain when I used Ubuntu.
