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

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class JellyMesh : MonoBehaviour
{
public float Intensity = 1f;
public float Mass = 1f;
public float stiffness = 1f;
public float damping = 0.6f;
private Mesh OriginalMesh = null, MeshClone = null;
private MeshRenderer renderer;
private JellyVertex[] jv;
private Vector3[] vertexArray;
void Start()
{
OriginalMesh = GetComponent<MeshFilter>().sharedMesh;
MeshClone = Instantiate(OriginalMesh);
GetComponent<MeshFilter>().sharedMesh = MeshClone;
renderer = GetComponent<MeshRenderer>();
jv = new JellyVertex[MeshClone.vertices.Length];
for (int i = 0; i < MeshClone.vertices.Length; i++)
jv = new JellyVertex(i, transform.TransformPoint(MeshClone.vertices));
}
void FixedUpdate()
{
vertexArray = OriginalMesh.vertices;
for (int i = 0; i < jv.Length; i++)
{
Vector3 target = transform.TransformPoint(vertexArray[jv.ID]);
float intensity = (1 - (renderer.bounds.max.y - target.y) / renderer.bounds.size.y) * Intensity;
jv.Shake(target, Mass, stiffness, damping);
target = transform.InverseTransformPoint(jv.Position);
vertexArray[jv.ID] = Vector3.Lerp(vertexArray[jv.ID], target, intensity);
}
MeshClone.vertices = vertexArray;
}
public class JellyVertex
{
public int ID;
public Vector3 Position;
public Vector3 velocity, Force;
public JellyVertex(int _id, Vector3 _pos)
{
ID = _id;
Position = _pos;
}
public void Shake(Vector3 target, float m, float s, float d)
{
Force = (target - Position) * s;
velocity = (velocity + Force / m) * d;
Position += velocity;
if ((velocity + Force + Force / m).magnitude < 0.001f)
Position = target;
}
}
}
