This is the web-resource module in atlassian-plugin.xml：
Since no helpful documentation has been found, I guess there are three directions at the moment:
- Existing front-end properties such as AJS or ConfluenceMobile may be able to get client information?
- It may be a resource dependency problem for the web-resource module, and there may be a web dependency that I do not know about.
- May be required by a back-end program to assist in obtaining client information, such as: according to the current URL of the pageId to the back-end to get its spaceKey or something else?
