Google Chrome (currently version 88)

Hello. I'm not sure if Google implemented this feature in a recent previous version (such as version 87), but I know that this is a feature in version 88 of Google Chrome.

The worst idea that Google (no offence to them) has ever implemented in their technology. It's called:
Extensions Toolbar Menu (here's an image of it: https://cdn.tgdd.vn/hoi-dap/1177886/chrome4.jpg )

It is the most inconvenient and annoying option which is forced on, by default. It makes managing 3rd party extensions almost impossibly annoying to manage. There's no way to disable Extensions Toolbar Menu within Google Chrome.

Yet thank God I found a method to disable it through the Google Chrome shortcut within Windows.
(look at the 2nd attached image below).
This is the highlighted part which disables that terrible feature:
--disable-features=ExtensionsToolbarMenu


...BUT there's still a slight inconvenience!!!
(oh great) <- [sarcasm]

Here's the problem
Suppose that I start up Google Chrome from a different method,
such as:
a) a website shortcut file (example.url)
b) an app called Howard which opens Google Chrome and takes me to my email account
c) etc.
Suppose that I open Google Chrome in the above methods, then the annoying Extensions Toolbar Menu will load up with Google Chrome.

So I gave it some thought, then all of a sudden, randomly, my brain though up of a possible solution!! But you gotta help me out on this.
If I can somehow implement the "--disable-features=ExtensionsToolbarMenu" line into the Default Apps feature of Windows (refer to the 1st attached image). Is there a registry entry that can help me modify that?

Thanks!

Found it! As of now, the solution I found seems to be working well.

Found this link: How to find the default browser via the registry on Windows 10 - Stack Overflow
and edited the Registry entry at: HKEY_CLASSES_ROOT\ChromeHTML\shell\open\command

When I went there, I found:
(Default) | "C:\Program Files\Google\Chrome\Application\chrome.exe" --single-argument %1

I was curious about "--single-argument %1". So I did the research to see what that means, and concluded that this is definitely recommended to keep and not remove. So I kept it there.

So now I tried adding: "--disable-features=ExtensionsToolbarMenu" after the "%1", then tried opening Google Chrome using the app named Howard (to go to my email account). The Extensions feature still opened up. No good. Let's try again.

I tried putting "--disable-features=ExtensionsToolbarMenu" in between "--single-argument" and "%1". The Extensions feature still opened up using Howard. No good. Let's try again.

Let's hope the last possible alteration works!
I tried putting "--disable-features=ExtensionsToolbarMenu" in front of :"--single-argument". Opened Google Chrome using Howard, AND YES! It actually worked this time! The Extensions Toolbar Menu did NOT load! That is perfect!
I hope this post helps other people in the future.


And to note: I actually have a 3rd party extension within Google Chrome named Extensity. I've been using it for years. It works very similarly to the feature I disabled above. Google's "Extensions Toolbar Menu" is a very inconsistent version of the 3rd party extension Extensity, hence I'm assuming that their version of this idea is "odd". I'm guessing it should work exactly like Extensity, but it doesn't! Extensity allows you to easily enable and disable 3rd party extensions in Google Chrome.
