Hey guys! I have a question maybe more like a doubt. Anyway, say, I'm making a game and I'm selling an nft collection on opensea. And I want that nft to be the Avatar of the player. So when anyone buys an nft on opensea, they should be able to use that nft in the game ie the nft's svg should automatically appear in the game when the user connects their wallet to the game. This nft should be more like an entry pass to the game. I need to know how to do that. I've gone through opensea's docs and I found there is some kind of retrieve function but I don't understand it.
