README.md

How to open MS Teams Links with the PWA

Linux:

1. Install Teams as PWA: https://support.google.com/chrome/answer/9658361?hl=en&co=GENIE.Platform%3DDesktop
2. Modify desktop entry of PWA:

   desktop_file=$(find ~/.local/share/applications/ -name chrome*)
   sed -i -E 's/Exec=(.*)/Exec=\/usr\/local\/bin\/msteams.sh \1 %u/g' $desktop_file
   echo "MimeType=x-scheme-handler/msteams;" >> $desktop_file

3. Download msteams.sh and move to /usr/local/bin
4. make it executable chmod +x /usr/local/bin/msteams.sh
5. Register protocol/mimeType
   • run xdg-mime default $(basename $desktop_file) x-scheme-handler/msteams
6. install Tampermonkey and ms-teams-links.user.js:
   • download Tampermonkey for chrome or Firefox
   • install ms-teams-links.user.js by clicking the "Raw" button above it and pressing "install" in the prompt

Troubeshooting:

• Check if mimeType works: xdg-open msteams://teams.microsoft/link/to/meeting
