Unable to use approve button

[kartheekgj]

Hi,

i followed the steps provided in the documentation to add the approve button in the interactive web reporting but unfortunately i could not see the button comming up. I see backstop remote running sucessfully but when i open http|https://127.0.0.1:3000 donot show the report.
I tried running the backstop using backstop test and when i run the backstop openreport it says its not open to public. When i open the backstop remote it says its rendered but not opening anything. Also where can i change this port number 3000 to anything else. I couldnot find this in the documentation anywhere. Can you provide an example where the approve/reject button is implemented
I can see this has been added somewhere here
https://github.com/garris/BackstopJS/blob/master/remote/index.js
But how to enable this or should we add this as a button and then do the call from the report?
