Changing Text Mesh Pro Text in World Space using C# Script

So, I made the Player Health Number show in the UI using TextMeshPro: https://youtu.be/U_Xcy24wp1Y

This is the Script I used:

using UnityEngine; using TMPro;

public class HealthText : MonoBehaviour {

 public PlayerHealthManagement _playerHealthManagement; //Needed to access the Information about the Player Health
 public TextMeshProUGUI textMesh; //The UI-Text GameObject that Displays the Current Player Health

 // Use this for initialization
 void Start ()
 {
     //textMesh = GetComponentInChildren <TextMeshProUGUI>();
 }
 
 // Update is called once per frame
 void Update ()
 {
     textMesh.text = _playerHealthManagement.playerHealth.ToString(); //Display the Player Health
 }

}

I also want to Display the Number of Health Points over the Player's Head, too.

What do I have to Change (except for

• using 3D Object -> Text Mesh Pro Text instead of UI -> Text Mesh Pro Text

• Using a Different Name for the Script )

in order to Display the exact same Text (in this Instance, the Health Points) also in World Space?
