If anyone needs to replace just the button, the part number is: Panasonic EVQ-PLHA15.

(you can also find variants with harder or softer click in the datasheet)

To desolder gently push a sharp point of tweezer or knife under the button, alternate melting the pins on one side while gently lifting, apply very light pressure and be careful not to lift the PCB pads.
