Help needed to remove the drawer under oven

I need to remove the large drawer that is under the oven from my 2017 Warwick Duo (photo below).
I have removed other drawers by lifting up a little when they are fully extend and this has allowed me to remove them.
However, I can't see any way to remove the large drawer.  I hope I don't have to unscrew the runners?

Can anyone say the best way to remove the drawer?

Need to undo the screws on the runners at side of drawer, runners stay attached to inside of housing. To replace need to raise drawer to correct level before reattaching screws

If the runners don't have the wheel at the end, screw removal is the way.

Thanks, you are both correct.
The screws (4 each side) have to be unscrewed.  I put CD cases under the drawer to support it and this makes refitting easy.

On a side note, these catches that AS use are just awful.

Like the CD case trick. Must remember that
