How to read text from a raw Dropbox text file in CircuitPython?

Question

I am trying to read a text file from Dropbox on a Raspberry Pi Pico with CircuitPython using adafruit_requests. The file should be available to view and download "for everybody who has the link". When I enter the url with ?raw=1, it leads to a website containing only the string of text.

I connected via Wifi and ran

from adafruit_requests import get
response = get("https://www.dropbox.com/s/<content_ID>/file_name.txt?raw=1")
content = response.text

Now, when I ran

print(content)

I got the following output:

<!DOCTYPE html>
<html>
<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Dropbox</title>
<link href="https://cfl.dropboxstatic.com/static/metaserver/static/css/error.css" rel="stylesheet" type="text/css"/>
<link rel="shortcut icon" href="https://cfl.dropboxstatic.com/static/metaserver/static/images/favicon.ico"/>

</head>

function read_cookie (name) {
        var nameEQ = name + "=";
        var ca = document.cookie.split(';');
        for (var i = 0; i < ca.length; i++) {
            var c = ca[i];
            while (c.charAt(0) == ' ') {
                c = c.substring(1, c.length);
            }
            if (c.indexOf(nameEQ) === 0) {
                return c.substring(nameEQ.length, c.length);
            }
        }
        return null;
}
function localize() {
    var locale = read_cookie('locale');
    if (locale) {
       var msg = message[locale];
       if (msg) {
           var elem = document.getElementById('errorbox');
           if (elem) {
               elem.innerHTML = msg;
           }
       }
    }
}
localize();
</script>

Obviously, this is not the .txt file I uploaded to Dropbox, but an error message.

Is there a way to read the raw text file from Dropbox into a variable of type string in CircuitPython?

Note: When I use my Laptop and regular Python 3, I can easily obtain the string I want by executing

import requests
response = requests.get("https://www.dropbox.com/s/<content_ID>/file_name.txt?raw=1")
content = response.content

(Here, I am using response.content which, in the CircuitPython example produces the same error message as response.text but encoded differently. The two modules are not identical in their output.)
