I don't see any option on the alerts to test them and see how they would work when live. I want to make sure they sound okay, if the animations of the gifs work, etc. etc.
There is a play button next to each alert type in the right column that should fire a test for the corresponding alert type
I'm using the pre made studio (skipped the set up). When I click on the 'Main layer' and then the 'Alerts' a menu to the right opens. Size/position, General, and then Alert types. Each has a little play button next to them and that seems to make it play a test alert.
Sorry if this isn't helpful! I'm just as new to it, haha.
