Failing to find Collection Id For High Volume NFT

Hey team. One of my partners is not seeing their collection Solana Monkey Business Gen 2 through our integration.

When looking up the collection ID from the Hello Moon page, I only see the SMB Gen 3 and Gen 1 collections. It's very weird because Hello Moon supports the Solana Monkey Business marketplace.

The collection has millions in volume here is the SOL scan to take a look

Really, if anyone could help me find the collection ID for this NFT, that would be super huge. Also, if I'm doing something wrong, maybe other people can learn from my mistakes.

Thanks in advance,
Logan
