Accidentally sent Ecomi to Trust Wallet under ERC20 Ethereum Chain instead of Go-chain

I sent Ecomi (OMI) tokens from Bitforex to the Trust Wallet, but I accidentally forgot to change the chain from ERC20 (Ethereum Chain) over to GoChain. I’ve gone through the steps of recovering, but I’m stuck on step 3 through step 5. (see link below)

I tried to import a new wallet with the private key (where the ‘lost’ funds went to on the Ethereum ERC20 Network) but OMI is a custom coin that you have to insert on the Trust Wallet App. so I’m not sure how to get those lost Omi coins off the ERC20 chain and back into my wallet as OMI Token on the GoChain.
