I can't find GetRandomPointInNavigableRadius() in GetNavigationSystem()

[Anonymous_8bfc49d357ba7b528ef55c187d3de2ea]

In my book

FNavLocation RandomPoint;
if(GetWorld()->GetNavigationSystem()->GetRandomPointInNavigableRadius(ThisController->GetPawn()->GetActorLocation(),5000.0f,RandomPoint))

but error : class"UNavigationSystemBase" has no member “GetRandomPointInNavigableRadius”

I’m already written in code

#include "Runtime/Engine/Classes/AI/NavigationSystemBase.h"
#include "Runtime/NavigationSystem/Public/NavigationSystem.h"

How to get and use “GetRandomPointInNavigableRadiu()”??
