How to display the contents of a folder on a Joomla 3 web page?

Question

PHP

Greetings friends, in general, I have such a task at work - it is necessary to display the contents of a folder (in the form of a list) on a site running Joomla 3 CMS, which is located on a separate FTP server.
That is, the page displays all the contents of the directory, any user entering the page can navigate through the directory and its contents + has the ability to download files from this directory to his PC.
How can I organize this whole thing guys? I would be very grateful.
PS:
At the beginning I thought of somehow stirring up with Google Drive, but all attempts ended in disappointment, since when inserting an iframe (), only the display of the contents of the folder in the cloud is added, when you click on the folder, it does not go to its contents on the site page, but there is a transition directly to Google Drive.
