What is this type of "screw" called?

[DW79]

Hello,

I have some inner windows that are held in place by a small plastic screw, as shown in the picture. Some of these have fallen off or broken, so I'm trying to find new ones, but not knowing what they're called makes it nearly impossible to find. A smart alternative would probably work too.

Does anyone know?

Could these work?

There are billions of different fasteners that are simply made for the customer and do not exist as "standard."

Yes, just need some type of spacer since the window rests on top of the "karm" so you need to raise the bracket a few mm. Thanks.
