The "Related" page of FileSelect says in one sentence These dialogs can be displayed via DllCall as demonstrated at GitHub., however that GitHub page only has v1 code for this demonstration. Therefore it kinda doesn't fit to v2 docs and needs probably example code written specifically for v2 or only remove the GitHub link (but the part where it mentions that other dialogs can be displayed via DllCall() is worth to keep, even if we lack example code, just for educational purposes).
