Hi @AlexUdy-2254
According to your case description, you want to let users join meetings via QR code.
Unfortunately, we feel regretful to inform you that mobile device users need to download and install the Teams app to join meetings or calls. Even through the link generated by the QR code, users still need the app to participate in the meeting.
Then there are account requirements: Even if users are able to join meetings through a browser, they usually still need a Microsoft account. This means that guests may need to create an account unless they already have one.
