Complex classes like DocumentModel often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use DocumentModel, and based on these observations, apply Extract Interface, too.

It seems like the method you are trying to call exists only in some of the possible types.

Add an additional type-check:
Only allow a single type to be passed if the variable comes from a parameter:
