Yeah I don't think that's possible either
Instagram is indeed a popular medium and is used by many people but recognizing them on NFT through Instagram media I think it's just a waste of time because other NFTs will be born that imitate this NFT just to get their benefit and spam will occur because they create and upload it freely and publicly.
Let's see if this can actually happen to Instagram, because so far NFT has started a lot of uncontrolled spam so that it can pollute the good name of Instagram which is also very popular even though it is not in the crypto space.
And in general I'm also not very fond of NFT at this point although I still use Instagram a lot on a daily basis.
