GPTs Actions: Two encountered during use

Using GPTs to customize my own gpt, I am currently running into two issues.

Problem 1: I defined Actions, and when gpt automatically executes into an interface defined in Actions, it always automatically asks the user if external calls are allowed. Whether you can not ask the user.
Problem 2: The image address returned by the interface in Actions, gpt always displays the address in the form of text, how to set the gpt to display in the form of a picture.
Hope you can get help, thank you.

you need set x-openai-isConsequential false

I have tried setting it up, but after the setting is completed, there will be an option that is always allowed, but it still needs to be manually clicked.
