Auctioning an NFT I own on a contract not owned by me?

Apologies for ignorant question ahead of time.

I wanted to understand, is it possible for me to auction an NFT that I own but on a contract that I do not own and was not created on Manifold Studio?

Also a follow up question, I created a test contract on Manifold and minted a token but can’t seem to find it when I go to create a listing

This is the contract https://etherscan.io/address/0x38870939cefd328bb77fd4263a65b44acb104764#code

Thanks in advance

For your first question, Manifold Gallery only supports mainnet ERC721 tokens minted in Manifold Studio that you own in your wallet, so it is not possible to auction an NFT on a contract that you do not own and was not created on Manifold Studio.

Additionally, at this time we don’t support gallery listings on testnet.
