Playtest install issue — code for Xbox Series X but I have Xbox One

I was invited to playtest FC 26 but I’m having an installation issue. When I applied I said I would use cloud gaming to test the new FC beta. I received an Xbox Series X code for the playtest, but I have an Xbox One. To use cloud gaming I must install the game first, but I can’t install it because the listing shows “Xbox Series X” only — not “Xbox Series X / Xbox One.” Please add Xbox One as a supported platform so I can install the game and stream it through cloud gaming to playtest it in Xbox Series X mode. Thank you.
