On mine push one button down and you can see an indent line in the inner surface of the other. Use this with a screwdriver to lift that button up and out and then release the depressed button and lift in the same way. Replace is reversal.

On mine, the button is surrounded by a silver ring.

It's a bit slippy, but the ring unscrews and that gives you access to the cistern.
