Call informations from a custom form made in blueprint

Hello,

I have created a form with blueprint in the grav admin for a specific page. I needed a list system, so I've decided to create my own form. Now I don't know how to call the data from this form in a page template...

I tried to find some informations about this subject, but I don't see anything about this on the website.

I want to use the name of the worker and the history (Like the image url {{ image.url }}) ! Here's the form blueprint bellow :

form:
fields:
tabs:
type: tabs
active: 1

  fields:
    gallery:
      type: tab
      title: Worker

      fields: 
       header.worker:
          name: Worker
          type: list
          style: vertical
          label: Add a new worker
          fields:
            .name:
              type: text
              label: name
            .history:
              type: text
              label: history

Thank you so much !
Kind regards

The information is stored in the page header. So call page.header.worker and its properties.
