If you're a Mac user, you might encounter problems while trying to share your screen. This is because your browser needs the permission by the Mac Operating System (OS). This can be solved quickly.
Open the System Preferences app.
Go to Security and privacy.
Choose Screen recording from the left menu and make sure the box is checked next to the browser you are using.
If you are unable to change these settings, you must first click on the padlock at the bottom left.
