How do you load a Widget by File from within a Plugin's Content Folder?

Trying to reference a file from within a plugin’s content folder within some C++ but I cannot figure it out.

Some of my attempts are as shown below

 static ConstructorHelpers::FObjectFinder<UClass> testObj(TEXT("Blueprint '/ExamplePlugin/Content/ExampleWidget.uasset'"));

FStringClassReference test = IPluginManager::Get().FindPlugin(TEXT("ExamplePlugin"))->GetContentDir() / TEXT("ExampleWidget.ExampleWidget");

Can anyone point me in the right direction?
