I am very sorry in case I ask a repetitive question that has already been answered before. I have been at this for more than 12 hours now but none of the posts I have read or articles I have consumed seem to point to what I need to do. ChatGPT can’t seem to help me either. 
So I have a Zap ready and in place which I wish to integrate with ideally a custom GPT which I have trained and use it to create and send out a sequence of emails. The issue is that even though I have trained the custom GPT and then also an OpenAI assistant, I cannot for the love of my life figure out how to get Zapier to talk to it? The custom GPT won’t connect to Zapier and the OpenAI assistant doesn’t seem to be able to hold its memory to dish out email scripts that are customised.
Any help will be appreciated!
