Possible to open docx files in Word Online when double-clicking them in a synced desktop library?

I have a solution I rolled in Chatgpt. It would probably take someone that is familiar with C# and Visual Studio to run. Maybe you can find one of your employees and get them to run it. I was going to try to charge you guys but it only took me a couple of minutes. Cheers and I hope this helps. 

using Microsoft.Win32;
using System;
using System.Diagnostics;
using Microsoft.Win32;

class Program
{
static void Main(string[] args)
{
RegisterFileAssociation(".docx", "WordOnlineRegEditor", "Open .docx files with YourAppName");
}

static void RegisterFileAssociation(string extension, string appName, string description)
{
using (RegistryKey key = Registry.ClassesRoot.CreateSubKey(extension))
{
key.SetValue("", appName);
}

using (RegistryKey key = Registry.ClassesRoot.CreateSubKey(appName))
{
key.SetValue("", description);
using (RegistryKey commandKey = key.CreateSubKey("shell\\open\\command"))
{
commandKey.SetValue("", "C:\WordOnlineRegEditor.exe \"%1\"");
}
}
}
static void Main(string[] args)
{
if (args.Length > 0)
{
OpenInWordOnline(args[0]);
}
}

static void OpenInWordOnline(string filePath)
{
string wordOnlineUrl = "https://word.office365.com/";
string fileUrl = Uri.EscapeDataString(filePath);
string fullUrl = $"{wordOnlineUrl}/?wopisrc=OneDrive&wdFirstNav=1&wdAllowInteractivity=False&FileUrl={fileUrl}";

Process.Start(fullUrl);
}
}

Total opposite of what has been asked.

I'm surprised that there isn't many replies to this post, as many businesses are moving to O365 and looking to save costs by only applying E1 or F1 licenses. We have a workforce of differing skillsets and they just want to be able to open a document in a simple manner at the end of the day.
