How to create siblings card on window?

I watch this video from docs anki.
In the video, I see them creating siblings card. But I don’t know how to create them in anki window. Help me.

The steps for Anki for windows are the same he shows in the video.
Did you try to replicate it?
If so, which step did you not understand?

In recent versions you can add a new card type by clicking on Options in the top right of that screen.
