any way to get in to an account you forget the email of?

ive had like a million different tiktok accounts and a million different emails over the years and ive been logged out of an account that has stuff on it from when i was 12 and i cant get back in because i forget which email i used. i remember the username and the password but not the email and it won’t let me sign in without verifying the email. the way it’s formatted is like [first letter]***[last letter]@gmail.com and i can’t remember what’s between. is there a way to bypass this or even just download the data from my account (tho its private)? or even any web tool i could use to scroll through a list of gmail accounts and try identify mine lol
