How to use MIT license in design, video, graphical, physical goods

[UDKodr]

With the MIT license requiring a copy of the license in the "software" how would we do that with things like social media posts, videos, merch, products for sale, etc?

Do we just add the copywrite to it?
Like in the description, and the product design (at the bottom for instance) and omit the attached license as there is no software?

I also noticed that the assets on Figma were:

Licensed under CC BY 4.0

so while I could just use those sets I was trying to use the whole zip found here if possible.

Thank you for your time and response I just want to make sure I follow the rules
