Question Check if mouse click was handled by ImGUI in regular Update() call?

I have a script attached to the camera which allows the player to move the camera by clicking and dragging anywhere on the screen. I also have a little piece of ImGUI which uses a `
GUILayout.BeginScrollView()`, but the problem is that dragging the scrollbar in the ScrollView also drags the camera.

Is there some way I can check in the camera script that ImGUI has already handled the mouse event, so that I can ignore it?
