Hi @Kiska, John ,
In my experience, you don’t need to install Teams client on your computer if you want to attend Teams meeting. If the meeting organizer shared meeting link with you, you can click the Teams meeting link and join it as a guest. After the organizer approved your request in the lobby, you can enjoy your meeting now.
For more details about how to join Teams meeting via link, you can refer to:
