TWebFilePicker

Is it possible to open the dialog by code? For example from any menu?






There is no "official' call for this in web browsers. This is simply an omission of browser implementation most likely driven by security concerns. There exists some "hacks" where you'd basically hide the WebFilePicker() element and call its click method.
