Free-For-All

I'm having some trouble, and I'm hoping you good people can help me out. How does one find out what modpacks contain a specific mod? Without having to say download them all individually and look through the mod folders?

More specifically, I'm trying to figure out what modpacks contain the "Deep Dark Dimension" or "Underdark" BUT for 1.16+? (The dimension where you need to stay in light to avoid taking damage, and also it contains treasure mimics, which is what I find really fun about it). I was playing an FTB pack (Revelations) that has the Deep Dark Dimension, but it's 1.12. :(

From what I understand the deep dark dim is from the "Extra Utilities 2" mod, but that's where I'm starting to get confused a bit, and any help would be appreciated. Thank you!
