[Question] - UrlLoad and UrlSave

hi,

Grapesjs is a fantastic bit of software and I've been playing with it for a week or so now. Im struggling a little with the urlLoad.

storageManager: {
    autosave: true,
    setStepsBeforeSave: 2,
    type: 'remote',
    urlStore: '/rest/V1/aware/save/:page_id', 
    urlLoad: '/rest/V1/aware/getJson/:page_id',
    contentTypeJson: true,
    headers: { Authorization: 'Bearer TOKEN' }
}

Im using an end point which is returning json as you can see here:

How I've read the documentation, is this supposed to load the layout into the canvas?

What I'm trying to do, is use the endpoints to save the canvas - and load the canvas etc. But on load nothing happens, I'm left with a blank canvas. Really appreciate if you could point me in the right direction, or a demo etc.

thanks
