imac a1419 keyboard, mouse, and dongle if appl.

Hi there.

Regarding: iMac A1419 (Late 2012).

I need compatible:

Rechargeable wireless numeric keyboard

with Mouse

(and Dongle if applicable)

Is the possible? I have been swirling around for hours trying to find. Lot's a sellers do not specify compatibility.

Can someone direct me to buy options please?

Thanks, ny
