Documentation Missing for WebGL Debug Symbols

There seems to be a lack of documentation for debug symbols. It feels like what i have found is along the lines of "enabling debug symbols on your build will allow your build to download debug symbols". While that is somewhat informative, it really fails to paint the whole picture.


1. How do i create debug symbols for a build (do i create them manually?)
2. Where do i upload them to after i create them (Cloud Diagnostics / Manage Symbols is my guess)
3. How do i assure they are downloaded into my game? Is there any configuration needed? How does Manage Symbols page know which debug symbol package is for what build?


If anyone knows the answers or has documentation that would reveal it, please let me know! Thanks!
