I am trying to make a Cradled FAB using Jetpack Compose Material 3. Based on the images from the documentation on this site: https://m3.material.io/components/bottom-app-bar/implementation
However in the code I can not find anything about where to specify the anchor position or set the fab to docked. The example code is XML and I'm using Compose. How is this done? I'm using Scafold and BottomAppBar now but they don't seem to have any options to dock or cradle or anchor the Floating Action Button.
