Still having popup messages do not disturb is on (?)

[jookornvdb]

For one tv channel there is no app so if i like to watch a program from that channel I watch it via my laptop, connected with a hdmi cable with do not disturb on. But sometimes i still get a 'pop up' on the side of the screen with, the last time, iCloud message. The last time it was a iCloud message from 'Privédoorgifte' (i do not find the english word for it, not on the web and not in my head ;-).
Can I disable or enable ALL but absolutely ALL, really ALL ;-) the messages so that 'do not disturb' is really, but really Do Not Disturb.
Thanks in advance for you input.

Have you checked your notification and focus settings in System Preferences?

Specifically (in your case): whether notifications are allowed when mirroring or sharing the display and whether time-sensitive or notifications from specific people or apps are allowed even while Do Not Disturb is turned on.

Thanks for your reply, but that's not it.
