Enums in NetworkList for Netcode

Hi, I can't seem to get Enums working for NetworkLists. My understanding based on the Documentation is that t$$anonymous$$s should implicitly work, and if I try using the same enum type in a NetworkVariable there's no issues. But when I try to use it in a NetworkList, I get the error: The type 'Gun.GunType' cannot be used as type parameter 'T' in the generic type or method 'NetworkList'. There is no boxing conversion from 'Gun.GunType' to 'System.IEquatable. What do I need to do to get Enums into a NetworkList?
