Help with the latest Redactor, removing formatting options

In the past I’ve managed to remove a few formatting buttons from Redactor but am having trouble with the new version.

The goal is to remove ‘quote’, ‘code’ and ‘heading1’ from the formatting-dropdown. (see attached).

So far I have tried various ways of inserting this from the documentation:

['p', 'h2', 'h3', 'h4', 'h5']

This is the only attempt which hasn’t resulted in a syntax error, but which has resulted in the formatting button disappearing completely!

  "buttons": [
    "html",
    "formatting: ['p', 'h2', 'h3', 'h4', 'h5']",
    "bold",
    "italic",
    "unorderedlist",
    "orderedlist",
    "link",
    "image",
    "video"
  ],
  "plugins": [
    "fullscreen",
    "video"
  ],
  "linkNewTab": true,
  "toolbarFixed": true
}

Please could you spoon feed me the json as I cannot seem to find the answer anywhere. Thanks in advance for your help!
