No, that’s the new "Local Network" prompt which started appearing since macOS 15. Any app that opens a multicast/broadcast socket (mDNS, SSDP, WebRTC ICE, etc.) now has to ask. Electron apps (including Notion) do this by default, so you see this dialog.

Feels like a bad default, it teaches user to ignore and say yes.

I believe that, broadly speaking, from all but the most scrupulous app developers' point of view, it is a good thing for users to blindly agree to permissions. This is obviously true if they are doing something nefarious, but even true if not, since every user who denies a permission to your app is a user who might be writing a nasty review about such-and-such an advertised feature that doesn't work. I hope very much that my OS will make it easy for me to behave in a security-conscious way—a hope that is almost always disappointed!—but I do not even bother to have such a hope for all but my most beloved apps, which are often beloved for exactly that reason.
