slack unfurling link with attachment blocks included

Question

So my goal is to include an image, with buttons, in a message. However, the file is not public and files_upload method takes away the functionality of the buttons, issue similar to this https://github.com/slackapi/bolt-python/issues/411.

While working on the solution to 1. upload the file, 2. unfurl the permalink, I managed to make it work but the output is not what I would like:

I would like the unfurled link image to appear under the blocks while keeping the blocks in the attachment section. Is this achievable? Also, the only time I can unfurl is to include the link within the test section, can this be changed? Sourcecode:

upload_resp = slack_client.files_upload(
                initial_comment=uploadfiles["initial_comment"],
                file=uploadfiles["file"],
                filename=uploadfiles["filename"],
                filetype=uploadfiles["filetype"],
                title=uploadfiles["title"]
            )

attachments = [
                {
                    "blocks": [
                        {
                            "type": "section",
                            "text": {
                                "type": "mrkdwn",
                                "text": "*Hi !*" ,
                            }
                        },
                        {
                            "type": "divider"
                        },
                        {
                            "type": "section",

                            }
                        }
