iOS app rejection because account security

Continuation of this thread, because I can’t answer to my own topics…
OK, so I created a separate account, specifically with no authenticator so it will not be blocked by anything when tested by Apple. I am sending game time to this account as gifts from my main account, and I am levelling Demon Hunter there.
Yesterday I managed to send first version of my app to Apple, with credentials for this new account, and it got rejected because testers could not log in, as the account was flagged for login from different… continents probably…
What do I do now? How can I have an account with lvl30+ character (needed for raiding) that can be accessed without security checks by me and testers at Apple?
