Binance USDT - Metamask, how to go back to Binance?

I transferred USDT from binance using the right network and it is showing in my metamask. Now I want to move it back to Binance but its saying I need Eth for gas fees.

I have Eth on another network and it doesn’t give me the option to add Eth to the Binance network?

How do I send the USDT to Binance?!

Send some BNB to your MetaMask wallet which your USDT is there . new update dont accept ETH for fee you need BNB.
