I tried to set "Shift + double-click", but it didn't work. "Shift + Ctrl + W" works. The software for the mouse is called "Logitech Options", maybe you can find instructions for the double click somewhere. :)

The double-click (with desired modifications Shift, Ctrl, Option, Command) can be found in "Logitech Options" under "Advanced Click". There, the keys can also be stored differently according to applications (Firefox, Finder, etc.).
Logitech Options is a programme that can be downloaded from https://www.logitech.com/de-ch... and also works well with Mac operating systems.
