Hi Vapi Team! I am trying to get my vapi agent to book appointments to my GHL calendar. I integrated GHL using the O-auth method, I created the tools, added the tools to the agent as well, but vapi out right can not find slots to book appointments to GHL, ven though I have all the calendar days open. So I signed up for Vapi this month, I am quite new to it, which is why I am not sure if I have not set up something correctly or if the issue is on Vapi's end. This is super urgent as we are launching our ad campaign in just a few days and we will be using Vapi to reach out to our prospects. Whatever info you need from me, I'll gladly provide. Thank you.
