How to find Web resource key for start sprint dialog?

Hi there,

I am new to plugin development and am currently working on creating a plugin that adds information to the sprint start dialog. I ran into a gap where I can’t find the web resource key for the sprint start dialog.

I have tried using the Web Fragment Finder plugin to locate the key, but it didn’t show anything. I am using Jira version 7.13.

Please tell me what else I can do to solve my problem.

Thanks in advance for your help and participation!
