I tried this, but my work uses MS Teams, which doesn't honour do-not-disturb. When you set DnD on, the app STILL flashes it's taskbar icon, creating a distraction. The only way around it is to mute all the noisy teams channels, and to remember to unmute them later. Also, being @-ed in a chat totally overrides DnD as well, and the sales guys have worked this out, and @ people constantly all day long.
I even tried not having Teams running when I was 'in the zone' only to end up being called on the phone to check 'whether I was working today'... :(
