Where do I install Custom File Input Panels for CC Bridge?

I am trying to install the CustomPanel_allWidgets.xmp sample xmp file on a Mac in Adobe Bridge CC 6.1.0.115.

I've tried about every application and user folder combination for Library ▸ Application Support ▸ Adobe ▸ XMP ▸ Custom File Info Panels ▸ 4.0 to no avail.

Please advise.

Thanks!
