How do I make the NFTlinker example in the repo both ways across chains? #42

i.e. not just from one chain to the other but back again

The NFTLinker example we provide already supports returning assets from the destination chain to the source chain.

Check out https://github.com/axelarnetwork/axelar-examples/blob/main/examples/evm/nft-linker/NftLinker.sol#L99C25-L102. When we send a token from chain A to B, we lock on chain A and mint on chain B. When you return the asset to chain A, we burn on chain B and unlock on chain A.

I hope you find this useful
