Currently, I am using this type of docstring with Flassger which works fine:
"""End Point to create something
---
parameters:
- name: body
in: body
type: string
required: true
- name: token
in: header
description: an authorization header
required: true
type: string
responses:
200:
description: Some description
"""
And I am able to send the request from ui like this:

But I need to make the token parameter global on this page, so that the user only need to fill this just once. What do I need to do to achieve that?
