I want to listen for a change of perspective in the 3d area, maybe can use msgbus api.The code I try as followed.But it does't work.How can I choose the correct properties.

def notify_test(*args):
    print('change123')

subscribe_to = bpy.types.RegionView3D,'view_rotation'
bpy.msgbus.subscribe_rna(
        key=subscribe_to,
        owner=object(),
        args=(1, 2, 3),
        notify=notify_test,
    )
bpy.msgbus.publish_rna(key=subscribe_to)
```

    Yup I think the only one which will work here is the 3D view handler. The depsgraph doesn't get updated when the viewport camera moves and I wouldn't count on msgbus. – Gorgious Feb 25 '24 at 09:45
