Trouble removing front Control panel

I have a Thermador PCS364GD I have front left burner sparks but no ignition. I don’t smell or hear gas when knob turned. I think it is the gas soldnoid valve. I don’t see the 2 screws on bottom corners to remove control panel pleas help… Bill

Maybe there are no screws on the bottom of the front panel I don’t see any. Do the 4 nobs and holders come off to get the front panel off.
