Parcel shelf broken on 2015 estate

[Lukeogroves]

Hi all! I bought a new car recently and the parcel shelf is broken on the end where it ‘clicks’ into position when pulling fully out. It looks like the plastic part has snapped off on one side. I’ve tried epoxy resin to glue it back but it’s not ideal. When u push the parcel shelf down to release the shelf, you can see the broken part moving as if it will snap again. I wondered can you replace the entire ‘end’ or if I really need a total new shelf? Thanks for your time.
