They can be found both on the same documentation page, but it seems to be the same. You know the difference from a functional perspective? What is the benefit using one over the other?

Thanks first for reading.
From the documentation:
The sidenav components are designed to add side content to a fullscreen app.
VS
The drawer component is designed to add side content to a small section of your app.
^ Emphasis is mine
The difference between the two components is that the sidenav component should be used for a global drawer (like a navigation drawer) while the drawer component should be used for content specific to the small portion of your app (such as allowing the user to filter files).
