how to open the bonnet on my 1994 renault espace Alize?

Lifting the bonnet release lever below the steering wheel does not open the bonnet catch there is spring tension in the lever as it springs back in place when grip released.I cant find a plate or tag to press under the center of the bonnet and cantsee where any bonnet hook catches are located.It seems like there are 2 catches 1 either side just inside the headlights but where they engage I cannot tell
