How do I SetTextureOffset in LWRP?

Hello. I'm trying to offset the texture and I'm using the example script from here : https://docs.unity3d.com/ScriptReference/Material.SetTextureOffset.html I'm using the light weight render pipeline / universal render pipeline. It doesn't work. I get no errors, but nothing happens at all. I just want to know what I need to type to offset the texture instead.

     using UnityEngine;
     
     public class Example : MonoBehaviour
     {
         // Scroll main texture based on time
     
         float scrollSpeed = 0.5f;
         Renderer rend;
     
         void Start()
         {
             rend = GetComponent<Renderer> ();
         }
     
         void Update()
         {
             float offset = Time.time * scrollSpeed;
             rend.material.SetTextureOffset("_MainTex", new Vector2(offset, 0));
         }
     }

EDIT: It doesn't seem to work with any of the shaders that are listed in the folder "Lightweight Render Pipeline". However, if I pick another folder "Unlit > Textured" it works fine. All the other shaders I can select display a purple colour (because I guess they don't work with the LWRP).
