Please add one or two lines of explanation in the PlayCanvas User Manual, on this issue below.

The names don't match. I do find an entry related to this in the user manual.

What I'm trying to say is ---- I came from Unity. In Unity, the script name in the inspector must be the same with the name in the scripts folder, or there will be an error. Today, I was learning from Will's code on 3D Gaussian Splat Annotations, from his project I took the first screenshot. When I saw a script in the inspector named annotationManager, I was trying to find one script with the exact name in the assets folder. But there isn't. I'm very interested in PlayCanvas so that I spent time to figure it out. However, the PlayCanvas user manual should add some explanation on this -- why the script name in the inspector sometimes does not match the script file name in the assets folder -- so that later new users won't be so confused as I was.
