I bought Minecraft Dungeons on the old mcd launcher, but when I try to play it on the mc launcher, it just says buy now. I know the reason is because I bought mcd on a different account, but is there any way to transfer it to the account I currently use?

Edit: From what I have seen, there is now way for me to merge/transfer accounts sadly. Its a minor inconvenience, but an annoying one at most. However, I did get Minecraft Dungeons working, so this issue is now resolved.
