Only first level Pages view

[inscrut]

Hello!

Installed the extension, everything is fine.

I didn't write anything in LocalSettings.php, all parameters are default (may be?)

On the main page I placed:

{{#network:
 | options=
{
    "nodes": {
    "shape": "image"
},
"groups": {
    "bluelink": {
        "image": "https://.../mediawiki/resources/lib/ooui/themes/wikimediaui/images/icons/article-rtl-progressive.svg"
    },
    "redlink": {
        "image": "https://.../mediawiki/resources/lib/ooui/themes/wikimediaui/images/icons/articleNotFound-ltr.svg"
    },
    "externallink": {
        "image": "https://.../mediawiki/resources/lib/ooui/themes/wikimediaui/images/icons/linkExternal-ltr-progressive.svg"
    }
}
}
}}

(Because i use short url)

The graph is displayed. But I have a question, I will give an example from your video: https://www.youtube.com/watch?v=iI1zJ8ma474

There is a main page and links on it, they are drawn around the main page. Let's call it "the first level of pages, number 1"

But when I click the left mouse button once on Talk:Main Page I expect to see the second level of pages (I highlighted the group under number 2 in blue).

The following pages do not appear for me, if I click the mouse button twice - I open this page.

Question: how to make the graph continue to draw pages like in your video?

Thank you!
