Question about mods and Steam compatibility

I downloaded the Historical Players Mod, but I purchased the game through Steam and can't find the "Draft Day Sports Pro Football 2020" folder in the Wolverine Studios folder in Documents.
Is there an alternative place I am supposed to place the mod because I got it through Steam? Thanks in advance for your help.
