隐藏图像附近的反应按钮，并在chatbot webhook messenger中设置文本链接

I've created a simple chatbot webhook for messenger and it works. What I want to do is:

1. to hide react button near my image attachment I sent (because takes some space from it: https://prnt.sc/oszvak).
2. to set description for links, found in text, I send (ex: "Google" insted of "www.google.com").

========================================================================

What I tried:

1. I looked for in developer tools documentation, but I didn't find.

My json I use to send image attachment messages:

json_encode(array(
    "recipient" => array(
        "id" => $senderId
    ),
    "message" => array(
        "attachment" => array(
            "type" => "image",
            "payload" => array(
                "url" => $url
            )
        )
    )
))

2. I found on internet this format <link|description> (ex: <www.google.com|Google>). But messenger displays it all as plain text.

My json I use to send text messages:

json_encode(array(
    "recipient" => array(
            "id" => $senderId
        ),
        "message" => array(
            "text" => $message
        )
    )
))

Do you have any idea how to resolve these two points? If you need, ask for clarification.
