How to enter the color files into Microsoft office 365 on a Mac

When I downloaded the business power point template from graphic river the author’s help pdf asks to move the color Copy all the XML files that are in the folder “XML Color
Files" to this folder:
C:\Program Files\Microsoft Office\Document Themes
15\Theme Colors

How do I do this procedure on a Mac computer? I have ms office 365 installed on this Mac.
Thank you.
