FREE coin support?

Would like to ask if Trust Wallet has any plans to support FREE coin in the near future? I was able to import the coin details into my wallet, and then successfully sent some from the exchange to my wallet, but it’s now prohibitively expensive to swap them on the Uniswap or Sushi dapps. It would be great to be able to swap them for (say) ETH within the wallet app.

Please how do I use the crypto currency say bnb
I have worth bnb in my watch wallet buh don’t know how to swap or use it
