How to access ILiveLinkSource->GetSourceStatus() via BFL

I’m creating a plugin which main purpose is to access this “GetSourceStatus()” function of an existing object via blueprints.

In common, is there any way to create a connection between native c++ class object and managed/reflected functions/classes?

I’ve already tried to cast ULiveLinkComponent* obj to ILiveLinkSource, but got a compiler error.
