Add a Vendor to Vendor List

A client uses this plugin for their cookie banner, and recently, one of their other plugin vendors has made their plugin GPDR compliant. To Enable the personalization features and cookie tracking, they told us we have to add them (‘CMI Marketing Inc. d/b/a CafeMedia’ GVL ID 996) to the CMP approved vendor list. I don’t see a way to do this through the plugin. Is this something that needs to be done through an account on CookieYes? Any information would help thanks!
