Managing sound and video settings during Teams meetings and calls for optimal communication
a poor man's workaround (perhaps mentioned here before?):
in order to mute my side but still listen through the Shokz, change the microphone in the Teams [settings>device settings, then on the microphone pull down choose a different microphone from the Shokz (typically your default microphone)] and then mute that other microphone.
Then if you want to speak you can either use that other microphone buy unmuting, or using a few more clicks change back to the Shokz microphone and then speak.
kind of trivial but does the job for me.
