I am wanting to make a custom title bar for my application. I am using c++ and WebView2. since I have some experience in making a website I thought this would be the best way to go, but I just can not manage to remove the default windows title bar.

Notion Title Bar

Notion for example has a custom title bar in the style that I am going for.

Using c++ it seems impossible to get a resizable window that keeps it's rounded corners and dragging attributes.
