How do I make two physics bodies not collide with each other?

I have some enemies on my platform game who throws some grapes at the Player.
The enemies are never alone, but next to others and everytime they throw the grapes, the fruits collide with each other.

Is there any way I can make the grapes ignore the collision with other grapes?

On the bottom of the physics behavior is layers and masks. It’s unrelated to the scene layers. You can put objects on the same layer(s) and/or masks.
