openAPI description (YAML) for ChatGPT integration required

Hi,

I want to connect a custom GPT to awork. I have come as far as being able to connect to awork using an API key and with the following API definition (YAML), I am able to ask ChatGPT to tell me something about the users in our account (getUsers). However, the three other functions in the YAML are not working (getTimeEntries, getProjects, getTasks) and I want to actually have ChatGPT event create or change things in awork.

Now, I am not asking for a debugging of my GPT-generated YAML, I am just wondering if anybody has already successfully connected a custom GPT to awork and can give me a hint how to do this?

Cheers,
Christian
