In your link is this explained:

"Search for your MetaMask wallet address on Etherscan (or the corresponding block explorer if not on Mainnet), open the dropdown menu, and there will appear all of the tokens and NFTs that you own."

If i checked now

https://etherscan.io/address/0xca599eadb12633a45575a9920964f5b586993435

there is nothing... but there must be minimum 5 nfts


"You can see all of the transactions performed with your NFTs by clicking "ERC-1155/ERC-721 Token Txns"

Cant found this option on eherscan... 

Thanks!
