Should previous games be installed to import their levels onto Hitman 3?

I want to buy Hitman 2 digitally on ps4 to get the access pass because I lost my Hitman 2 disc. Unfortunately, I don’t have a great internet, and downloading all of it is gonna be painful. Is downloading previous games required or will access pass be granted just by buying them?

I think installing previous games is not required.
You just have to have them in your library of the same account, and the system should see you’re eligible for merging games.

But isn’t it better to buy Access Pass for HITMAN 3 directly?
Or you want to own the previous game?
