Trust wallet is rubbish, use a better one, please. BlueWallet or Blockstream Green are excellent mobile Bitcoin wallets.

What wallet do you have the bitcoin in? I'm guessing a custodial wallet, since you can't move the sats on-chain.

Just install Muun wallet, it's non custodial and once received, you'll be able to send the sats over both, the LN or on-chain.

There's a fee to open the channel but I believe, it's cheaper than any swapping services.

All three wallets I've mentioned are non-custodial (except the LN part of BlueWallet, unless you connect ti to own LN node). This means, you're in the charge at all time. It also means you're responsible for the keys, create backups of backups to make sure you always have an access to your money.
