### Checklist
- [ ] Is it a bug fix
- [ ] Is a typo/documentation fix
- [x] Is a feature enhancement
- [ ] It is a refactor
- [ ] Created tests that fail without the change (if possible)
- [ ] I ran and tested this change locally — I did not rely on CI to
find out whether it works
- [ ] This PR has a single purpose (not a fix + refactor + feature in
one)
- [ ] This change is a trivial fix, **OR** it links an issue the NetBird
team agreed on beforehand. Changes to the public API, gRPC protocols,
functionality behavior, CLI / service flags, or new features always need
that agreement first. See
[CONTRIBUTING.md](https://github.com/netbirdio/netbird/blob/main/CONTRIBUTING.md#ticket-first-pr-second).
