There used to be an option to hide the left ribbon (e.g. list of all teams) to expand the content you are looking at on the right hand side in your MS Teams interface. Why has this disappeared and how can I get it back?
When I am presenting, I don't want to share the left ribbon, but rather focus on the content I am presenting on the right.
This is the icon that is now missing
this is what it looks like now after it disappeared
