You need to remove the inside panels from behind the seats.

Undo the securing bolts for the seatbelt reels.

There are 2x 10mm nuts holding on the strip from the inside.

Remove these nuts, them remove the screw from the underside of the wheelarch's.

Give the strips a good pull to remove them.

The panels are then clipped at the bottom.

A good pull should get them off.
