Currently, I am utilizing the mat drawer sidenav and content components on my webpage. Within the sidenav, there is a button that I want to display above both the sidenav and the content sections. Unfortunately, no matter what I try, the button keeps getting obscured by these elements. For reference, you can check out this Stackblitz.
Ideally, I would like to find a solution that allows me to position the button properly without having to alter the CSS styles of the material wrapper elements.
