[ENG-9603](https://linear.app/comm/issue/ENG-9603/make-it-possible-to-sign-message-with-olm-account-from-user-keys). This is an example on how to use it, probably this code can be updated, exported and used in Restore Flow (cc. @tomek). This is real-life use case, because we take previous Primary Device `deviceID` from device list history, then sign message using Olm Account from Backup without extracting `deviceID`, and use `deviceID` from device list to verify - so if this passes verification both device list, and User Keys upload/download/crypto operations work together. Depends on D14046
