Regarding Skoda Fabia mk2 - Front Left Door Handle Backing plate / Door Handle Mounting Bar

Dear Experts , Can any body please advice if I am missing anything , I am trying to fit the door handle backing plate on front LEFT side , the fitted parts OEM is 5N0839885H as seen on ebay https://www.ebay.co.uk/itm/188844016752 www.skoda-parts.com I can see it had 1 screw under handle on left end of backing but nothing is on right side , After tighting the 1 screw the backplate does not get any support on right side and loose, so when handle is pulled it come out. Any idea how to make sure it fits correctly on door so that handle does not come out. I can see two holes on door , one hole is used for handle stopping as seen in the video https://www.youtube.com/shorts/_bPG7CQmjz0 ( older versions has screws but not any more ) but there is no nut on back plate to hold the 2nd screw on right side . I suspect the door or backplate compatibility issue any help would be highly appreciated ! Attched Some photos for info. If some body have replace backplate images from repair manual please share.

Thanks

kind regards
