I`ve recieved usdt on TON blockchain

I`ve recieved usdt on TON blockchain by mistake.I tried to get private key in hex with Github https://github.com/toncenter/tonweb-mnemonic.Then i found Lumos and tried to put private key but it didnt work and im not experienced enough to tell why.So how can i deal with this problem?
