What I've done is substitute all the variables of "RingCentral for Mac" for "RingCentral Meetings" and while this has worked for me for RingCentral Phone, it keeps failing at a few different steps for RC Meetings and I'm not sure how to proceed. Could someone help as another set of eyes/tell me what I could be doing better? Here is my error log:
