Can someone give me some pointers for initiating a function on an incoming call immediately? I have an assistant with the ServerURL prefilled with a webhook in Make. I have the Server Messages set with 'tool-calls' and 'function-call'. It doesn't fire immediately on the call, but will trigger shortly after depending on the conversation. The webhook works and returns the info I need but I just cant find a way to have it do it right off the bat. Thank you in advance!
