9.91 how to get value of ENUM_SET from MaaS SMAX?

I've upgraded to Connect-It 9.91 and noticed in java debug that the MaaS connector can finally retrieve values of ENUM_SET fields from SMAX custom entities. However, I haven't figured out how to access those values. 

For example, field RequestType_c in custom entity Software_c can store one or more values from ENUM_SET, and has 1 = CompanyPortal_c. I see that MaaS connector considers this field as text and in Java Debug it returns JSON value of "RequestType_c": ["CompanyPortal_c"]

However, if I try to access that in a mapping script, such as [RequestType_c], the value is empty string.

Anyone know how to access these?
