How to remove end padding of checkable menu item?

I have an overflow menu with a checkable menu item. I would like to align the checkbox all the way to the end, but I don't know how this can be done. My menu is defined like so:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:icon="@drawable/ic_baseline_more_vert_24"
        android:title=""
        app:showAsAction="always">
        <menu>
            <item
                android:id="@+id/desktop_site"
                android:checkable="true"
                android:checked="false"
                android:icon="@drawable/ic_baseline_desktop_windows_24"
                android:title="Desktop site"
                app:showAsAction="never" />
        </menu>
    </item>
</menu>
