Beko Bif22300w – control panel access

This oven has a double layer control panel with the screws for the switch and t/stat are behind the first one.

I’ve just done the elment on it and noticed the control knobs were loose. I quickly tried to gain access to tighten the screws but what little time I had I couldn’t.

I’m sure I’ve done one before but I didn’t want to force anything and cause damage. I tlooks like it should just pull out after moving the metal tangs but it doesn’t. Can anyone give me a quick tip or let me know what I’m missing ?

I notice Beko no longer use this system for the control panel or use the large fan blades. Had lots of BIF series ovens with the fan blade catching on the element as it moves with age. A PITA to be fair.
