Spacemacs-esque leader key?

Hiya! I’m very new to Kakoune type keybindings, so I was wondering if, with Dance, it’s still possible to define keybindings like Spacemacs, where <space> is a leader key to do all sorts of things. If so, how can I do this?

So basically for text editing I’d still use Dance, but in normal mode etc I am able to use <space> as a leader key.

The API for named menus has changed. Now, args should be { "input": "leader" }.

Ah that package.json had the answer, I ended up with this:

 {
    "key": "capslock a",
    "when": "editorTextFocus && dance.mode == 'normal'",
    "title": "Insert at line end",
    "command": "dance.modes.insert.lineEnd"
  },
