Am I missing parts for my OEM Roof Mould installation?

[jma8774]

Hey, I'm new to this forum but I would like some help from all the experts here regarding an installation of the Mazda CX-5 2022 Roof Mould.

Parts:

• KB7W-50-9H0B (url to part)
• KB7W-50-9L0B (url to part)

I see that each of the roof mould have 4 small things that look like they're supposed to latch on to something but I don't see anything like that. Does anybody know what is going on here and whether or not I am missing some parts? Thank you in advance for your help.
