TikTok Account Recovery Blocked by Hacked Gmail and Forgotten Phone Number

I have been unable to log back into my TikTok account on my Redmi Note 12 5G because the Gmail linked to my account appears to have been hacked. Since I lost access to this Gmail, I cannot receive the verification code that TikTok sends for login. I normally use my account from Thailand. To recover my account, I tried the option to get help from a friend and chose my friend for verification, but TikTok did not approve this method and did not allow the recovery of my account that way. I also no longer remember the phone number that was registered to the account, so I cannot use SMS verification either. I am asking TikTok to help me recover my account using my username and any other possible manual identity verification they can offer, instead of the hacked Gmail or the forgotten phone number. I would like my account to be given back to me securely so that I can use it again.
