Any way to set drag events on a phaser 3 group?

I'm trying to set a drag event on a phaser 3 group, but I wasn't able to achieve what I want. I was reading some phaser 2 blogs, and they said that it isn't possible to set a group a drag event. Can somebody help me with this? It's really impossible to set a drag event to a group?

First lemme explain the group behaviour here, the group game object does not have any shape or body as it is basically an Array of game objects Array<gameObject>. so it doesn't have any input events assigned.
