Neochat snap doesn't show SSO login options which makes in unuseful

When you select in neochat SSO login option, it is supposed to open the link

in the browser.

But for some reason it doesn’t.

The SSO login still works if I find neochat port

$ ps -fe | grep neochat
$ netstat --all --program | grep 'NEOCHAT PID' 

and then replace XXXXX for neochat port in url with the port number for example 12345

My questions are:

  1. Why snapped neochat doesn’t open my browser (firefox provided by EndeavourOS from pacman)
  2. Why neochat from pacman can open my browser ?
  3. What to do to configure snapd url opening in browser ?
