StateTree_PropertyRefExternal_Handle Help - No valid constructor?

Hello,

I want to create a TStateTreePropertyRefExternalHandle for my TStateTreePropertyRef, but the compiler says that there is no valid constructor for this.

Am I missing something? Or how can I use the TStateTreePropertyRefExternalHandle for getting the FStateTreeExecutionContext outside of the overwritten functions

MotivationHandle = TStateTreePropertyRefExternalHandle(MotivationRef, Context);

This is how I try to create the Handle
