Automatically run other set APIs first and use their responses in the API request

When sending an API request, it would be nice to be able to call other APIs registered in the collection in advance and use the specific value of the response in the request set as a variable (set directly without using an intermediate variable).
The ability to set a variable and have it automatically call another API and set a value in the response.
For example, when I call API A, I need to put Access_token in the header, and when I call A, it automatically calls the API that gets the Access_token and gets the access-token from the response and automatically sets it to A’s request (header) or A’s request bodies. I think this is already supported by many other REST clients (Insomnia etc).

Hi, I don’t fully understand this case. It would be helpful if you could provide your screenshots or help docs of Insomnia.
