[ModX EVO] How to filter in ditto via tagging extender?

Question

MODX

Hello.
Such a task: display links to articles in two different blocks using the igra and schem tags.
Created a TV named tags, with checkbox type with possible values ​​igra||schem.
I added TV to the article template and selected the schem tag on certain articles, but for some reason all published articles are displayed instead of those marked with the schem tag. My request looks like this:

[!Ditto?
&id=`schema`
&tagData=`tags`
&tagDelimiter=`, `
&tagDocumentID=`[*id*]`
&tpl=`@CODE:<li><a href="[+url+]">[+pagetitle+]</a></li>`
&parents=`7`
&depth=`2`
&display=`20`
&paginate=`0`
&outerTpl=`@CODE:<ul class="list-unstyled">[+ditto+]</ul>`]

I will be grateful for your help!

Found a solution. Should have added &tags=`schema` and &tagmode=`onlyTags`
