How i make this mesh visible its gen thu c++ at run time

ok the mesh look like this:

now the code look like this

#include "SpaceGame.h"
#include "APlanetGeneratedActor.h"


AAPlanetGeneratedActor::AAPlanetGeneratedActor(const class FPostConstructInitializeProperties& PCIP)
	: Super(PCIP)
{
	TSubobjectPtr<UGeneratedMeshComponent> mesh = PCIP.CreateDefaultSubobject<UGeneratedMeshComponent>(this, TEXT("GeneratedMesh"));
	int radius = 50;
	int separators = 30;
	int e;
	//Contains the points describing the polyline we are going to rotate
	TArray<FVector> points;
	/*
	points.Add(FVector(20, 5, 0));
	points.Add(FVector(15, 6, 0));
	points.Add(FVector(12, 7, 0));
	points.Add(FVector(11, 8, 0));
	points.Add(FVector(8, 7, 0));
	points.Add(FVector(7, 6, 0));
	points.Add(FVector(4, 5, 0));
	points.Add(FVector(3, 4, 0));
	points.Add(FVector(2, 3, 0));
	points.Add(FVector(1, 4, 0));
	*/
	double segmentRad = PI / 2 / (separators + 1);

	for (e = -separators; e <= separators; e++)
	{
		double r_e = radius * FMath::Cos(segmentRad * e);
		double y_e = radius * FMath::Sin(segmentRad * e);

		for (int s = 0; s <= (4 * separators + 4 - 1); s++)

			double x_s = r_e * FMath::Cos(segmentRad * s);
			points.Add(FVector(x_s, y_e, z_s));
		}
	}
	points.Add(FVector(0, radius, 0));
	points.Add(FVector(0, -1 * radius, 0));


	TArray<FGeneratedMeshTriangle> triangles;
	Shpare(points, triangles, separators, radius);
	
	mesh->SetGeneratedMeshTriangles(triangles);
	//RootComponent = Shpare(vector);
}

}

now what i am missing why its not show

You declered component, but thats not enouth, you need to add component(s) in to Actor, by setting it as root component or use AddComponent function, so:

RootComponent = mesh;

its make at a mesh but its still an issue basiclly not working
