I am doing well, how are you?
This functionality is something we have as a built in integration. You will need to connect your GHL account on the integrations page, then under automations create a new automation with the GHL trigger "On Contact Created" followed by a next step of "Call Phone Number". You can populate the phone number field dynamically by pressing the "fx" button in the "Call Phone Number" node and selecting the phone number from "On Contact Created"
Please let me know if you have any questions.
