How to create draft entry with strapi v4?

To create a Draft entry, just append status:'draft' along with the other body params.

Unfortunately, it doesn’t works.
I use REST API from Ruby.
Send request with body like this.

    options[:body] = {
      data: {
        title: post.fields[:title],
        address: post.fields[:address],
        pinned: !!post.fields[:pinned],
        oldId: post.sys[:id],
        status: 'draft', # add this line
      }
    }
