is https://gist.github.com/gildor/82ec960cc0c5873453f024870495eab3#file-jetpackcomposescaffoldsnackbar-kt-L102 the best way to close the keyboard using a button? I cant find how to create or reference my own SoftwareKeyboardController. Is there no composable function for this

TextInputService can close a keyboard however there is some weirdness in the implementation since it checks for an auto increment integer.
