In order to get the Authtoken generated, we need to find the Accounts URL for the installed Analytics Plus.
Accounts URL can be found in the application console, under Help icon --> Product info --> Miscellaneous details.
Once the Accounts URL is found, Authtoken can be generated by launching the below URL:
<Accounts URL>/apiauthtoken/create?SCOPE=ZROP/reportsapi
Eg:- https://<hostname>:8200/apiauthtoken/create?SCOPE=ZROP/reportsapi
