“When I’m duplicating my display” activates when you have two displays active; toggle it on to allow either priority only or alarms only.
“When I’m playing a game” is self-explanatory; toggle it on again to modify it to priority only or alarms only.
“When I’m using an app in full-screen mode only” can also be set to prioritise or alarms only.
You can also set the priority to “For the first hour after a Windows feature update.”
When Focus Assist is enabled, a small moon icon will appear at the far right of your taskbar. You should be able to view any missed alerts if you click on it.
