My founders Cape has been missing from my account for a while

My 10 year anniversary cape or the actual name Founder's Cape has been gone from my account for years now. In 2020 (I think) I had a Google pixel phone and those phones got a beta to Minecraft Earth I played it for a little while with my Microsoft account connected to it and when I came back to my Xbox to play Minecraft the cape was gone. I've been thinking for a while that it was a bug and I would get it back but I never did. And recently I got back into the game and have been missing that cape. I'd really like this back if at all possible. It means a lot to me. I've taken a picture of what it looks like and attached it to this. I appreciate whoever took the time to look at this. Thanks
