Setting get to output from a specific category

Good afternoon, members of the forum.
I’m not bad at writing styles, but I don’t understand Ghost any more than I do English spelling.
What is the essence of the question.
There is a header, it is necessary to statically display 1 article from a certain tag, for example “supertag”.
I tried different methods, at the moment my code looks like this.

{{#get "posts" limit="1"}}
    <div class="special--promo-text">
        🔥<span class="colorwhite">Спецпроект</span>
    </div>
    <a class="special--promo" href="{{url}}" aria-label="{{title}}">{{title}}</a>
{{/get}}

This is how it looks in the picture:

The question is how to make it so that instead of the “empty field” the last article from the “supertag” tag is displayed?

I would be grateful for any hints.
Maybe this is revealed in the Ghost: The #1 open source headless Node.js CMS, but my knowledge of English was simply not enough; (

You want


{{#get "posts" filter="tags:[supertag]"}}

You can add the limit parameter too.

Thank you!
This works for me!

{{#get "posts" limit="1" filter="tags:[supertag]"}}
    {{#posts}}
    <div class="special--promo-text">
        🔥<span class="colorwhite">Спецпроект</span>
    </div>
    <a class="special--promo" href="{{url}}" aria-label="{{title}}">{{title}}</a>
    {{/posts}}
{{/get}}

If not for you, I would have lost my mind.
