Cannot sell SUPER on metamask

I setup Binance Smart Chain in metamask and my SUPER coin is there. I have the option to SWAP but not an option to SELL. Tried to setup Binance bridge but the site binance.org is not US based. Does anyone have any idea how i can get ability to trade my SUPER coin in Metamask? (update: I mean SWAP SUPER for ETH, but how can i pay fees if i cannot send anything to BNC smart chain in metamask?)
