Mandatory Credits?

I’m going to be releasing my first game in a couple of months, and am brushing up on all the red tape with Epic. I understand that Unreal/Epic must be credited using a specific template ("[Product name] uses Unreal Engine. Unreal is a trademark of Epic Inc…yada yada yada"). Does the credit mandatorily have to be in-game, or does it suffice to publish them on, say, the game’s product page on Steam? (It was a one-man operation, and I’d like to avoid any credits in the game itself.) I can’t seem to find any language on the matter online.
