the real issue you're having is that snap package only supports AMD64, not ARM64: https://snapstats.org/snaps/teams-insiders
Your best bet is likely to use a chromium-based browser and use Teams through that. Honestly, having to use teams on multiple platforms, this is the way to go, to avoid Teams' very terrible custom/annoying notifications and make use of the system-wide notification system.
You could try this version made for RPi: https://snapstats.org/snaps/teams-for-linux but it's supported architures only include armhf and amd64, so some work may be required to get it working well on the PBP, without the need to install armhf libraries. the devs offer an arm64 deb file you should be able to use: https://github.com/IsmaelMartinez/teams-..._arm64.deb
for anyone else using arch/manjaro, this is also available in the aur: https://aur.archlinux.org/packages/teams-for-linux/
