This is desktop app version v11.80.0 on window. I don’t know if this is a bug.
Comparing with the demo it didn’t ask for API Key but instead ask for bearer token.

After sending the request, it didn’t come back with a response and no error.
Hey @yatw888 
Welcome to the Postman Community! 
The video you mentioned is nearly a year old and many changes have been made since then.
I’m using the latest version and made a basic request with a token that I obtained from my account (https://platform.openai.com/settings/organization/api-keys).
