How to connect Zoom Pro to Facebook Group for Live Streaming

Hi when I purchased the zoom subscription I was told there is something special I had to do on Zoom to make it work.

2 things are happening right now: 

-Facebook wants me to copy a URL into Zoom and I don't know where to put that in my Zoom Account

-When I try to go live I get this error message on Zoom platform: #200 Subject does not have permission to create live video in this group - It's my group & I gave myself access so i'm confused on this - It is a private group
