I have a code by idk how connect it to the fbx model from blender

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class JellyMesh : MonoBehaviour
5. {
6.     public float Intensity = 1f;
7.     public float Mass = 1f;
8.     public float stiffness = 1f;
9.     public float damping = 0.6f;
10.     private Mesh OriginalMesh = null, MeshClone = null;
11.     private MeshRenderer renderer;
12.     private JellyVertex[] jv;
13.     private Vector3[] vertexArray;
14.     void Start()
15.     {
16.         OriginalMesh = GetComponent<MeshFilter>().sharedMesh;
17.         MeshClone = Instantiate(OriginalMesh);
18.         GetComponent<MeshFilter>().sharedMesh = MeshClone;
19.         renderer = GetComponent<MeshRenderer>();
20.         jv = new JellyVertex[MeshClone.vertices.Length];
21.         for (int i = 0; i < MeshClone.vertices.Length; i++)
22.             jv[i] = new JellyVertex(i, transform.TransformPoint(MeshClone.vertices[i]));
23.     }
24.     void FixedUpdate()
25.     {
26.         vertexArray = OriginalMesh.vertices;
27.         for (int i = 0; i < jv.Length; i++)
28.         {
29.             Vector3 target = transform.TransformPoint(vertexArray[jv[i].ID]);
30.             float intensity = (1 - (renderer.bounds.max.y - target.y) / renderer.bounds.size.y) * Intensity;
31.             jv[i].Shake(target, Mass, stiffness, damping);
32.             target = transform.InverseTransformPoint(jv[i].Position);
33.             vertexArray[jv[i].ID] = Vector3.Lerp(vertexArray[jv[i].ID], target, intensity);
34.         }
35.         MeshClone.vertices = vertexArray;
36.     }
37.     public class JellyVertex
38.     {
39.         public int ID;
40.         public Vector3 Position;
41.         public Vector3 velocity, Force;
42.         public JellyVertex(int _id, Vector3 _pos)
43.         {
44.             ID = _id;
45.             Position = _pos;
46.         }
47.         public void Shake(Vector3 target, float m, float s, float d)
48.         {
49.             Force = (target - Position) * s;
50.             velocity = (velocity + Force / m) * d;
51.             Position += velocity;
52.             if ((velocity + Force + Force / m).magnitude < 0.001f)
53.                 Position = target;
54.         }
55.     }
56. }
