Symbolic Name of the bundle for DOR sample



A bit of a noob question. I am trying to use the package at below link to generate document of record at the click of a button.

Adobe Experience Manager Help | Using API to generate Document of Record with AEM Forms

I have downloaded and configured the package and created a service "user data" to be used with the service. I now want to add an entry to Apache Sling mapper service. Could anyone tell me from where I can find the symbolic name of the bundle that I need to input at this step?
