Put shelves up

I need two sets of shelves to be up. 1) Two basic ones that I have the screws etc 2) Two of the below. That didn't come with the screws/plugs. If you could please provide them. https://www.next.ie/en/style/su916741/g15694?gclsrc=aw.ds&gad_source=1&gad_campaignid=22309320626&gbraid=0AAAAADn-_y8ZOr6L-LAIewxZe_DG721Cc&gclid=Cj0KCQjwnIDUBhDrARIsAJDGwSta_Qjc8i3L7UAvvI44zqaKdtovACFfOs4f6ddtRQX-pWg5PwA-1dAaAmegEALw_wcB
