IT WORKED!
I have been trying to get this to work for literal years! YES!!! For any Mac users facing the same issue, it's in the file named "com.strayfawnstudio.niche" If you have two of these files, as did I, saves may be in one while the customizable files are in the other.
For anyone clueless on how to get there on a Mac:
Open finder
click go
hold down option to show library
click on library
open application support
find either your team niche file or the one mentioned above
and add your unique colors and or names
May nobody else have to do as much digging as I did, stay safe
