Chromium is not open Zoom by xdg-open

I installed Ubuntu 20.04 LTS, Chromium 81.0.4044.138 and Zoom 5.0.403652.0509. When try to open link to Zoom conference appears window "Open xdg-open?". Unfortunately nothing happened. I used tip from this topic but unsuccessful. Directly Zoom works. Chromium is default browser. Please help.

Solution 1:

This seems to be a bug in the new "snap" architecture. It breaks not only links to zoom, but other things as well (linke magnet links) The bug is documented here: https://bugs.launchpad.net/snapd/+bug/1776873

Hopefully there can be a fix soon, this is a pain (it used to work in earlier versions!
