I also think this process is not free, as you will need to pay fees for them to assist you with the recovery. Take a look at the table attached in the link. This process may also take up to 5 days.
Well,, you can give this a try, and if you come across anything, you can update us on what you did.
Good link, there is 80 USDT fee for recovering unsupported chains,
Also they mention that they will only send it back to the address it came from, so OP will have to contact binance as well if they are able to credit him for that.
Maybe they might charge a fee as well, but doesnt look like OP will get more then 80-85 USDT back regardless
