I
Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
I would expect either:
a. top "gold" cap to unscrew or pop off, revealing screw.
OR
b. "gold" piece at end of handles to pop off or unscrew.
OR
c. handles to unscrew revealing a grub screw.
