How to make an if condition in modx to display a menu?

Question

MODX

There is a piece of code that displays a menu (if any)

[[pdoMenu?
                                    &parents=`2`
                                    &level=`1`
                                    &where=`{"template":4}`
                                    &tplOuter=`@INLINE <ul>[[+wrapper]]</ul>`
                                    &tpl=`@INLINE <li><a[[+classes]] href="[[+link]]" [[+attributes]]>[[+menutitle]]</a>[[+wrapper]]</li>`
                                ]]

But how to make a working condition out of it, what if there is no menu, did it display the layout?

Examples from the docks do not give the desired effect

[[!pdoMenu:default=`<p>вывести этот текст вместо пустого меню</p>`?
                                    &parents=`2`
                                    &level=`1`
                                    &where=`{"template":4}`
                                    &tplOuter=`@INLINE <ul>[[+wrapper]]</ul>`
                                    &tpl=`@INLINE <li><a[[+classes]] href="[[+link]]" [[+attributes]]>[[+menutitle]]</a>[[+wrapper]]</li>`
                                ]]
