How to get or use names of UDF's in Octopus API

Using the SchemaRead endpoint, I have been able to retrieve a list of all the fields including UDF's. The problem is that the UDF's are identified by "/AbEntry/Udf/$TYPEID(23)".

How do I get the corresponding name so that I can know what field I am referencing or better yet, how do use the UDF name instead of the TYPEID()?
