Flow NFT Catalog and Testnet

[slyxby]

• I created public and private keys: flow keys generate.
• I visited the site https://testnet-faucet.onflow.org/ and paste the Public Key into the appropriate field. Аnd click the create account button.
• I published copies of the contracts (FungibleToken.cdc, NonFungibleToken.cdc, ExampleNFT.cdc, MetadataViews.cdc) on the testnet.
• I visited the site https://nft-catalog.vercel.app/v and add my ExampleNFT.cdc in form.
• On the second step I see an error - The provided contract, ExampleNFT, is not an NFT. Your contract must implement the standard NonFungibleToken contract.

What am I doing wrong (how to fix the error)? Why can't I add a contact from the test network? How do I add a test contract to a directory on the testnet?

What address is the NFT deployed to?
