Safety Line connect to GPSMAP 66i inreach?

I want to program Safety Line (https://slmonitor.com) to my Garmin 66i. On the Safety Line side of things, I've added the IMEI number to the satellite device. It seems as though my Garmin device has successfully programmed into the app. But I don't know the steps on how to access Safety Line on my Garmin device. 

I'm unsure how to proceed with this.
