Upload Media to X (formerly Twitter)

What’s the new process to upload a new Media to X (Formerly Twitter)? I don’t see the X (Twitter) v5 app available to add to my scenario anymore.

If I copy an X (Formerly Twitter) v5 module from another Scenario I have built and attempt to add a new connection, I get a JSON response with a “401 Unauthorized” message. The existing module in the other scenario still works to upload media.
