Grappling Hook/Arm in 2D

Hi This is my first time making a 2D platformer in Unity, and I'm not very good at coding. So that's why I'm here asking for help. The grappling system I'm developing has many differents parts, and I have broken them down in a requirements list:

• Instant pull the player (Fast like a dashing ability)

• Player can only use it once, and it replenish when they touch the ground.

• The arm can only shoot in two direction. Forward or Forward at a 30 degree angle. (So the player doesn't use the mouse) I made this Diagram to better explain what I mean by the player only has two option.

• If the arm doesn't hit anything, it will retract back to player. And then they have to touch ground, if they want to activate it again.

• If the player hit the edge of a obstacle, they will sling up over the obstacle and land top of it. ^^Like this ^^ So it is basically the same Grappling Hook from "Dying Light", but in 2D.

The player is made using a RigidBody2D, so my goal is to add force to my player in the direction of the grapplingPoint.

So far I'm just trying to create a raycast that shoots forward and then move the player to that point.

   if (Input.GetButtonDown("Fire1") && !wallGrab && !wallSlide)
         {
             isGrappling = true;
             GrapplingArm();
         }
 private void GrapplingArm()
     {
 
         RaycastHit2D hitInfo = Physics2D.Raycast(grapplePoint.position, grapplePoint.right);
 
         if (hitInfo)
         {
             Debug.Log(hitInfo.distance);
         }
 
         Vector2 grappleDirection = (grapplePoint.position - transform.position);
         rb.velocity = grappleDirection.normalized * grappleSpeed; //Move player to grapplepoint
     } 

But that doesn't work. So my questions are: How do I make this work? Or maybe should i try another method, like using the Distance Joint 2D? and if yes, will this method fulfill the requirements?

And now I just want to thank you for reading all this. And every comment will be much appreciated.

Small update: I tweaked the grappleSpeed and have now noticed that when i press the Fire1 button the player teleports to a point... And when the player jump and press the button, the player will be pulled down to the ground faster. Here's a video, showing what is happening.
