I am working on a demo version of a GHL Voice AI agent using Retell and am running into a blocking issue. In my current setup, a GHL workflow sends data to Make.com to fetch real-time availability for a discovery call. After this step, the same GHL workflow triggers a Retell outbound call. While Retell successfully places the call, it does not read the most recent availability returned by Make. As a result, the confirmed discovery call date and time are not reliably captured and sent back to GHL to create the calendar invite. Please help
