Adding a tabs-navigation to my plugin

Hi there, I have yet another problem: I want to have multiple tabs on the very top of my plugins window. However, I can’t get the tabs to work in my twig file. Some key Item seems to be missin, but I can’t figure it out by myself.

I tried it with the documentation of the shopware component library, stating to use the code

<sw-tabs>
    <sw-tabs-item>
        Explore
    </sw-tabs-item>
    <sw-tabs-item>
        My Plugins
    </sw-tabs-item>
</sw-tabs>

But I cant get it to display any Content whatsoever…

Can someone please help me?
