How to AddForce in direction of mouse-CodePudding

So I have been searching for over an hour, I am getting a headache lol. So I'm working on a super simple 2D game, everything is done basically. However, I don't have an android device or tablet. Therefor, I can't test out the controls properly. In the meantime, I still want to develop the game, so I decided to create a mouse input instead.

The controls are simple, you have a player object, and to replicate touch/swiping, click/drag/release.

Click and Drag in any direction
Release adding force in direction of mouse position in relation to PlayerObject position on release.

Kind of like just small pushes in any direction. How can I go about this?

EDIT: I made it apply force, but not how I desire. So with this code its using the center of screen as the base. So if I click in the bottom half of the screen its always forcing it down.

 mousePos = cam.ScreenToWorldPoint(Input.mousePosition);

    if(Input.GetMouseButtonDown(0)){
        Vector2 dir = new Vector3(mousePos.x - rb.transform.position.x, mousePos.y - rb.transform.position.x);
        Debug.Log("Applying Force in Dir: "   dir);
        rb.AddForce(dir * multiplier);
    }

If I understand you correctly you want to

MouseDown/TouchBegin on your object
Drag the mouse/touch in a certain diretcion to define a direction strength
Release the mouse/touch in order o apply force to the object according to the dragged vector

I would rather use

The objects with attached components

Cube
 |--BoxCollider2D
 |--Rigidbody2D
 |--DragAndReleaseEventHandler2D
 |--Example
Visualizer
 |--LineRenderer
 |--DragAndReleaseVisualizer2D (with reference to Cube's DragAndReleaseEventHandler2D)
Floor
 |--BoxCollder2D
