The best way to do this is to share your “Entire Desktop” with the students via MS Teams.  The link below is a video that shows exactly how and why to share your Entire Desktop in MS Teams instead of individual applications.  Sharing your Entire Desktop makes it much easier on you because you don’t have to “worry” about sharing individual items.  (Whatever you have displayed/open on your desktop- will be shared with the students watching the MS Teams Meeting/lecture.)
