Gassless transactions

I am currently trying to use defender relayer to send USDT tokens from 0 ethereum balance using node js.

what i did : created relayer adress and api key using defender (funded)
i am trying to find a straight forward code to send USDT from a wallet using private key to another wallet and make the relayer pay for gas.
Can someone guide me through please.
