To assign a collider on a prefab you need to do following steps:

Open the prefab and select the object you want to equip with a collider.

If you do not know, how you can create a prefab we recommend our tutorial creating prefabs.

Click on Add component.

3D colliders and 2D colliders

We recommend using 3D colliders.
