Redeemed Game on Wrong Account. Any Recourse?

I bought a code for Assassin's Creed Origins from Gamestop but accidentally redeemed it on a guest account on my Xbox. Is there anything I can do to get the game on my main account? I can still play it now of course through game sharing but it's annoying that I'll always have to remember the login credentials for this second account because of this one game. Microsoft chat support was no help.
