Noob to NFT’s with question

I have a 10% knowledge of NFT's/Crypto, so I'm sure I'm doing something dumb.

I have a MetaMask wallet, which is housing some of my NFT's. I claimed an All Star Game NFT (from https://app.poap.xyz/). I'm trying to get that NFT from wherever that's residing to my Metamask wallet.

I claimed it on the POAP site with my Metamask wallet address, but it's not appearing in my Metamask wallet with my other NFT's. I read Metamask doesn't always show NFT's so I linked my account to OpenSea to view and I still don't see it. Any help or guidance in the right direction would be appreciated! Thanks!
