Filling in the "previewUrl" in the GraphQL Response

I’m using the AWS S3 provider to upload my files to S3, then when I try to fetch that in the GraphQL, I notice that there’s a field called previewUrl: null, how can I use that field?
I believe that field could be helpful to set a friendly url instead of use the direct AWS S3 url, any ideas?

Thank you all
