nativefier --help and https://github.com/jiahaog/nativefier/blob/master/docs/api.mdBug description
*Edit: After reboot of system Icon was updated. Name is still incorrect.
The properties icon and name when right clicking on the Windows 10 taskbar is incorrect
the application name is shown as a function string:
function(str) {
if (arguments.length === 0) return this._name;
this._name = str;
return this;
}
Picture:

Steps to reproduce
Run nativefier on a Home assistant instance:
nativefier https://hass.example.tld -n "Home Assistant" --win32metadata "{\"ProductName\":\"Home Assistant\",\"InternalName\":\"Home Assistant\",\"FileDescription\":\"Home Assistant in an Electron App\"}" --tray --single-instance -i ./out.ico`
or just
nativefier https://hass.example.tld`
Run the nativefied application
Right click on the taskbar icon
verbose build output
C:\Users\Dugite code>nativefier https://hass.example.tld --verbose -n "Home Assistant" --win32metadata "{\"ProductName\":\"Home Assistant\",\"InternalName\":\"Home Assistant\",\"FileDescription\":\"Home Assistant in an Electron App\"}" --tray --single-instance -i ./out.ico
Running in verbose mode! This will produce a mountain of logs and is recommended only for troubleshooting or if you like Shakespeare.

Preparing Electron app...
Copying electron app from C:\Users\Dugite code\AppData\Roaming\npm\node_modules\nativefier\app to C:\Users\DUGITEC~1\AppData\Local\Temp\nativefier-11-53-6-app--1904-rv7JixWY0pxn
Writing app config to C:\Users\DUGITEC~1\AppData\Local\Temp\nativefier-11-53-6-app--1904-rv7JixWY0pxn\nativefier.json
No files to inject, skipping copy.
Updating C:\Users\DUGITEC~1\AppData\Local\Temp\nativefier-11-53-6-app--1904-rv7JixWY0pxn\package.json 'name' field to home-assistant-nativefier-787f8b
Converting icons...
Building for Windows and icon is already a .ico, no conversion needed
Packaging... This will take a few seconds, maybe minutes if the requested Electron isn't cached yet...
