[Schema Inaccuracy] The user type should be an enum

[masklinn]

I expect there are very few values for this property, but it's really unclear what they are or could be aside from "User", which is only given as an example.

Given OpenAPI supports enums, it would make a lot of sense to provide all possible values for this field, or at the very least properly document it to explain what its role and purpose is (or whether it's irrelevant, which doesn't seem to be the case assuming at least one of the other values is Org this could be useful for some interactions).
