[Feature Request] Please allow hiding the Extensions button in Edge toolbar

I am using Microsoft Edge version 140.0.3485.66 on macOS. In this version, the Extensions menu button (the puzzle icon) is forced to stay visible on the toolbar, and the toggle in Appearance / Customize toolbar settings to hide this button has disappeared.

I use some extensions, but I don't want the extension (puzzle) icon to show on the browser interface. 

You just need to roll back this feature to the state it was in the previous version. Keeping the Edge interface clean is a very good reason why I prefer Edge. I like using Edge instead of Google Chrome, and this is an important reason! I don't want you to make it more and more like Chrome!
