Thank you once again 🙏 I managed to get it to work (there is very little information indeed).

Thank you Quinn (big fan btw), I have tried to do it with an extension, which works surprisingly well, but for some reason the only way to get it to truly work was to present the remote view (tried both NSView/Controller representables) inside a popup. Trying to directly include it in the hierarchy results in a stale view (shows up the content but cannot be interacted with).

Disregard. This was an issue on my end.

Archiving & uploading with Xcode 13.2RC also resolves the issue.
