Question Can't seem to delete cloned prefab

So I'm trying to destroy the clone of the prefab that I instantiated but somehow it's not working

Code (CSharp):

1. public TextMeshProUGUI displayText;
2. public Canvas renderCanvas;
3.  
4. TextMeshProUGUI tempText = Instantiate(displayText, transform.position, Quaternion.identity);
5. tempText.transform.SetParent(renderCanvas.transform, false);
6. Destroy(tempText,1f);
