Hi Simeon,
Mike’s Tech Tips on Youtube has some really high quality videos on Bazzite. I can’t recommend the overall method he uses in the one on dual-booting Windows and Bazzite (he recommends disabling secure-boot temporarily and this can cause more problems than it solves), but the video does have a ton of quality footage - including video sequences of the exact steps you’re asking to see (the timestamp is at 647s, or 10:47, in case the forum embed doesn’t respect the stamped URL):
Good luck!
edit: PS, as this video is six months old it is certainly using the old key. You will of course have some variation in key name and password.
