Hi there,
Happy to see now Unlock works with existing NFTs 
I have a question though:
I am trying to configure a lock to work with an ERC-1155 NFT I previously minted on the Polygon blockhain (just as explained here: Unlock Launches “Bring Your Own NFT” Token Gating). In the “Wiring the contracts up to the hook" step, I must fill out the createMapping form of Polygonscan.
However, there is a _tokenTypeId (uint256) field that I must fill out to set up the mapping on the hook. I am not sure what value should I write, as in the Unlock instructions it does not appear. Any help would really be appreciated
