如何在ckeditor5中将光标移动到文本末尾

const editor = ClassicEditor
    .create( document.querySelector( '#editor' ) )
    .then( editor => {
        // 获取到 CKEditor5 实例对象
        console.log( editor );
    } )
    .catch( error => {
        console.error( error );
    } );

const position = editor.model.document.selection.getLastPosition();

editor.editing.view.scrollToTheSelection( { duration: 0 } );
editor.editing.view.focus();
editor.model.document.selection.selectPosition( position );
