Make a test call on the web version of Teams
In Teams on the Web, the Devices tab does not exist.
Therefore, test calls cannot be made in Teams on the Web.
Like the Teams desktop client, you need a test call from the web

If I'm borrowing a pc for a meeting I tend to just log inn using the web app. Running a test call beforehand would be very useful to verify that everything works.
