Apply Material (with custom texture) on procedural mesh

Hello guys, I am very new to procedural mesh generation + i am not a 3d modeler at all.
The problem i have is i can't seem to find a way to properly apply my material (having a custom texture) to my procedurally generated simple plane mesh.

Using this code to generate mesh

 public class MeshGen : MonoBehaviour
 {
     public int xSize;
     public int zSize; 
  
     Vector3[] vertices;
     int[] triangles; 
     Mesh mesh; 
 
     void Start()
     {
         mesh = new Mesh();
         GetComponent<MeshFilter>().mesh = mesh;
         CreateMesh(); 
     }
 
     void CreateMesh()
     {
         vertices = new Vector3[(xSize + 1) * (zSize + 1)];
         for (int i = 0, z = 0; z <= zSize; z++)
         {
             for (int x = 0; x <= xSize; x++)
             {
                 vertices[i] = new Vector3(x, 0, z); 
                 i++;
             }
         }

         triangles = new int[xSize * zSize * 6];
         int vert = 0;
         int tris = 0;
         for (int z = 0; z < zSize; z++)
         {
             for (int x = 0; x < xSize; x++)
             {
                 triangles[tris + 0] = vert + 0;
                 triangles[tris + 1] = vert + xSize + 1;
                 triangles[tris + 2] = vert + 1;
                 triangles[tris + 3] = vert + 1;
                 triangles[tris + 4] = vert + xSize + 1;
                 triangles[tris + 5] = vert + xSize + 2;
                 vert++;
                 tris += 6;
             }
             vert++; 
         }
     }
 
     void UpdateMesh()
     {
         mesh.Clear();
         mesh.vertices = vertices;
         mesh.triangles = triangles; 
         mesh.RecalculateNormals();
     }
 }

left one is simple plane in unity, and right one is my generated mesh (both having the same material applied). P.S i want my procedural mesh to look like plane (having the material & texture properly applied)
