When a participant in the call raises their hand you will see A) a little hand symbol on their tile (see the green arrows on the screenshot below) and B) on the Show everyone tab a Raised Hands section will appear. The participants will be listed in this section in the order they raised their hands in.
If a moderator presents while on a different tab, and a hand raises, they receive a sound notification.
Let’s say Adam Muster asked his question after having raised his hand. You then can simply position your mouse over the raised hand symbol and click on the Lower button that will appear.
If the moderator lowers a participants hand, they receive a notification.
