Go to Activity on start

Is it possible (or is there a uservoice) to set the Teams desktop client to go to the Activity tab then with a blank right hand panel when it opens for the first time on a machine boot after being closed (not just minimised) rather than going to the last Chat or other part of the system you were on? There are times where I need to open teams during presentations or when there are other people looking at the screen where I may have been having a sensitive conversation that I wouldn't want the application to open up on.
