Webapp.connectHandlers vs Webapp.rawConnectHandlers

I can’t find any document about those methods. I need to know the difference so that I could use it better. Thanks in advance :smiley:

rawConnectHandlers is just pure Connect
connectHandlers also includes stuff that has been added by app and packages as noted in this comment that initializes it:

  // Packages and apps can add handlers to this via WebApp.connectHandlers.
  // They are inserted before our default handler.
