Keymap.of binding to backspace is invalid

I want to bind the Backspace key to implement custom deletion. For example, when deleting the widget ‘table_one.AAA’, it should be replaced with ‘table_one.’. I am using Decoration.widget and atomicRanges for this purpose.
But I found that the ‘Backspace’ key cannot be bound using keymap.of or listened to using PluginSpec.eventHandlers .

Is changeFilter suitable？

finish：

const deleteWidget = EditorState.changeFilter.of((tr: Transaction) => {
    if (tr.isUserEvent('delete')) {
        console.log('deleteWidget');
    }
    return true;
});

It absolutely can. Is it possible that your binding ends up with a lower precedence than the default keymap?
