Custom Numbers with a .fmf skin

I have downloaded the Tato23 skin, which looks great, but I am wanting to use custom numbers I have made (EFL style) with the skin. However, as it has downloaded as a .fmf file, there are no folders for me to place the graphics I have made in.

Does anyone know how to make the graphics work? I have FM23 through Xbox Game Pass, so there is no resource archiver for me to use like I would be able to via Steam.

Thanks

Can i download it
