I usually go to the dev website and download there and throw it in a directory and make link
Little harder to update things sometimes but a non issue most times.
I totally missed the zoom tar crazy scroll down..lol.
Just started getting back into flatpaks enlighted myself last nite It was total train wreck flatpak apppimage
even snap (it was total mess would not even install.) even setup the beta site for flatpaks download zoom
