Nissan Micra K12 S- 2004 -- Interior Lamp?

Hi
I got some problem with the interior light of my Nissan Micra K12-S (2004) and the owner's manual explain how to open it, but it seems to be completely different as it should.
I managed to take it out from the top of the interior of the car but now hangs lose as I am not sure how can I refit it back?

The light is rounded plastic frame which can rotates with a switch on the side

Any help, please?

Thanks
