When using rememberFileSaverLauncher, it doesn't display a dialog allowing you to pick the directory and file name

If I use rememberFileSaverLauncher in Desktop compose, it will pop up a dialog allowing me to pick the directory and file name to save to.

In the browser version, it just saves straight to the downloads folder.

I'm not sure if this is platform specific behaviour (if so no problem) or a bug.
