Toilet cistern lid removal - no screw under push buttons

[StaffH]

Our toilet has stopped flushing so I need to remove the cistern lid to check inside. All the instructions I can find suggest there should be a screw under the dual push buttons. However when I removed the push buttons there isn't a screw head to undo but there is something that resembles a smooth headed screw, if there is such a thing!
I've tried pulling and unscrewing the chrome bevel without success.
Does anyone know what I need to do?

Undo the entire chrome bezel. Turn it anti clockwise and it will unscrew real easing the cistern lid.

Thanks Jon. Should I turn the bezel with the 2 rods pushed down below the bezel or leave them prominent as they are in the picture?

They will be fine as they are
