What kind of data would you like to map? My guess is that when we originally added the tag, there was no way of sending data to the tag (or at least this was not covered in the implementation guide).
If you could send us an up to date copy of the implementation guide by email, we'll see if any template updates are required.
Check out our new Swift integration library for iOS, macOS, tvOS and watchOS: https://github.com/Tealium/tealium-swift with updated documentation https://community.tealiumiq.com/t5/Swift/tkb-p/swift.
Another reason for not having a Mapping Toolbox is because the vendor doesn't require specific names for their data, which means each client could send data to different destinations. In this case it is impossible for us to know what destinations each client would like to use. Therefore we just leave the Toolbox empty.
However, this does not mean the tag does not support mappings. It just means you have to manually type in the destination fields.
Currently our template is set up to add all mappings into an object, and that object gets sent into the "RightNow.Client.Controller.addComponent" function as the first argument.
For Example, anything you map will get put into an object called "data." Then we will send the "data" object like so:
Hope that helps.
