Help with widget shortcode please!

Hello,
https://www.thenouveaustyle.com/

I want to make the posts that appear in my widget to be only my sticky posts, or only one category that I have called front-page.

These posts appear directly under the slider, but currently the widget shows all recent posts. I want the same 4 posts there at all times.

Here is what is in my text widget:

[tabs tab1=”Services”]
[tab1][recent_posts num=”4″ type=”post” meta=”true” thumb=”true” thumb_size=”small-post-thumbnail” more_text_single=”Read more” excerpt_count=”10″ custom_class=”posts” more_link=”blog” more_text=”See all services”][/tab1]
[/tabs]

How do I define category posts instead of recent posts?

Thanks!
