Apple ID login question…

When I signed into the game for the first time with my Apple ID, apparently I chose Hide My Email out of an abundance of caution. I want to un-hide my email so I can link my accounts and, maybe, have more control over my in game profile. I can’t seem to do it myself, but Apple said the app’s website might be able to do it, so I’m wondering if anyone here can do that for me? Can someone at Bubble Witch 3 Saga or King manually change the email associated with my game account/login?

TLDR: I want to change my game account email to my real email instead of the random one Apple assigned when I erroneously chose to hide my email at account creation… can anyone do that?
