How to upload, replace and delete multiple images to react-final-form

Question

I want to create, replace and delete 3 images within a form. I'm using react-final-form and just wondered how I would do this? I can get three file inputs on the page but figure out how to update each file in the array or delete them.

I would like my initial values to be something this:

{
  images: [{}, {}, {}]
}

Then upload one image

{
  images: [File, {}, {}]
}
