Hi there, I'm trying to enable Go native types in cel env setup, and I'm aiming to access the field name using a customized name via the cel tag. In the https://pkg.go.dev/github.com/google/cel-go/ext#NativeTypes, it says, "In order to enable this feature, pass in the EnableStructTag option." However, I can't find this option in the codebase. Can someone provide some guidance on this? Thanks
