Hey! I assume Spaces == Profiles. There is no way of syncing them at the moment. However, if you are willing, you can manually move over the relevant files and have your saved windows etc. just the way they were on your M1 MBP.
Saved windows are stored in a hidden file in ~/Library/Application\ Support/Orion/Defaults/.local_named_windows.plist Copying this file to the same location on your new device and restarting Orion should be all it takes.
For profiles other than Primary (Defaults in the path I posted above), you will have to figure out which UUID corresponds to which profile and make sure you copy over the correct saved window plist to each profile on your new Mac.
