In last test, when Teams aren't running and start clean cache, some data of authentication is cleared too.

Currently I'm not tested. Feel free to validate.

@MarekGajdosik and @maksimdzmitryew this "Teams for Linux" snap is a unofficial project that using Electron for deliver MS Teams. I beleive Microsoft removed Teams snap packages. I guess do a upgrade in snap option to support unofficial version.

Here is my first time on GitHub.
However, here is my contribution to this topic.
I have Ubuntu as my SO, and my teams-for-Linux is a fork on the Snap.

I changed lines 24, 25, and 26 to:

export TEAMS_PROCESS_NAME=teams-for-linux
cd /snap/teams-for-linux || exit 1

run ps to find your teams-for-linux process and you will see that:

$ ps -ef |grep teams-for-linux
me 324126 323853 0 12:32 ? 00:00:00 /snap/teams-for-linux/523/teams-for-linux --type=utility --utility-sub

So my teams-for-linux is on directory /snap/teams-for-linux
and the TEAMS_PROCESS_NAME is teams-for-linux and not just teams
