stop object at end of line then destroy

Unity Engine
1

I am in need of some help.
I have this script that destroys objects when the objects reach the end of the line.
I would like to change it so that when the object reaches the end, it first becomes unclickable, stops moving for 1 second, and then gets destroyed. This script would be for my very first game, still learning.

void Update()
{
thisTransform.Translate( Vector3.forward * gameController.moveSpeed * Time.deltaTime, Space.Self);

if ( thisTransform.position.z > gameController.laneLength )
{
if ( hurtTarget == false ) gameController.ChangeLives(-1);

gameController.objectsLeft–;

gameController.UpdateProgress();

Destroy(gameObject);
}
}

Use a coroutine. WaitUntil (() => condition), or WaitForSeconds. That would be one way.

You can use invoke.
Make gameObject.enabled = false, to disable any click over it .
Put the Destroy function inside invoke().

void Start()
   {
       Invoke("myfun", 1.0f);
   }

    void myfun()
   {
//called after 1 second
    }
