Let me describe more detail of the request.
We want to display some html content with two buttons when user clicks "Ok" button, after filling all prompt variables.
The html content will be made with a rest API return message.
The rest API will be requested with some variables inserted by user on trigger page.
The actual build will be started if user clicks "Confirm" button on the html page or pop-up.
Also this process should be executed under specific condition like the configuration is under a specific configuration.
