[Mac OS] DND enables when I focus WoW

Hi, I am playing WoW from Mac OS Big Sur 11.5 (last version) on M1 Macbook.

I have an issue with Do Not Disturb mode in Mac OS. When I focus World of Warcraft window DND becomes active. I didn’t notice same behaviour in any other apps, but WoW. Please, if someone had same problem, tell me how to fix this thing. It is really annoying because I do not receive any reminders and notifications from messengers. Btw, I have this issue only when Display Mode is Fullscreen (Windowed)
