I'm trying to embed an nft on a website and it doesn't work. using the nfts from this collection https://opensea.io/collection/south-polar-constellation

but if I use another nft if it works? that is not in the collection

I did some research and found out that NFTs which are minted on the Matic network will not work because embedded-nfts only work with the ones which are minted on the Ethereum network.
