Display Minecraft username instead of Xbox account name in drop-down menu

After migrating my account, the drop-down menu in the launcher to select different accounts, shows the Xbox account name instead of the Minecraft username.

because I have multiple accounts, I would find it more useful to see the Minecraft username there, so that I can easily decide what account to use.

I cannot change the Xbox account name to be the same as the Minecraft username because Xbox does not support underscores in the account name.
