I will finally sew a hidden zipper properly, using this foot

It doesn't work at all, I tried it on different machines, it doesn't sew the zipper at all, so I continue to use a regular one-sided foot, although I have several different feet for concealed zippers

I couldn't try it because it didn't fit the machine. The place for the screw is high, and the size to the screw is not ours
