1/1 auction on a Manifold page

I want to create an auction with my new 1/1 piece, I tried setting up test auction with an ERC-1155 token but it wont let me, if I have any unsold ERC-721, the Gallery app in Manifold will let me do that, is that right?

Thank you

Gallery doesn’t support testnet atm - Are these unsold tokens you’ve minted to yourself? Or tokens from a claim?

I still have not minted the erc-721 that will get auctioned but I will minted it to myself and then start an auction
