Speedmaster mk40 clasp button broken (1563/850)

Hi, just wondering if anyone here knows of how i may fix my clasp button.
Unfortunately one day my daughter kicked and somehow dislodged this small part in the clasp and pieces went flying. I got most of it back, but assume there is some sort of spring that helps push the button outwards to latch on.
I have provided photos of the part where i assume something is missing.

any help would be appreciated, thank you.

Replacement of the clasp is the only good option. You definitely do not want to loose your watch when the repair is not holding.
Clasp can be ordered separately from Omega, no obligation to also have a service.
