Task at hand: Work with multiple accounts using MS-Teams.
Currently MS-Teams does not allow to seamlessly switch between multiple accounts. For example, if you have a private MS-Teams account and a company account, you can not switch easily between those two. The Pidgin instant message client provided this functionality since decades. But MS-Teams from Microsoft does not offer this functionality.
One rather crude, but workable approach, is to switch the following directories on Linux:
$HOME/.config/teams$HOME/.config/Microsoft$HOME/.config/'Microsoft Teams - Preview'
If those directories are moved or deleted then you can start with a fresh account.
Needless to say, this will log you out. So you cannot keep two connections in parallel.
I learned about these directories by using /usr/share/bcc/tools/opensnoop. This program is part of package bcc-tools.
This program shows all files, which are opened by programs. In our case it showed:
