I am experiencing difficulties downloading files from channels where the bot is not present. Specifically, I am utilizing url_private along with the required authentication token and files:read scope. Although I am able to retrieve file information successfully, I encounter an issue where the file does not download when using the fetch function in Node.js. Interestingly, when I paste the same URL directly into a browser, the file downloads without any problems.

The file downloads successfully using url_private when the bot is present in the channel, whether I use the fetch function or paste the link directly into a browser. However, when attempting to download files from channels where the bot is not added, the file downloads via the browser but not using the fetch function in Node.js.
