Direct access a camera proxy

I have an RTMP camera feed coming into HA and have created a proxy to generate an MJPEG feed. I am able to add and see both of these video streams on the Lovelace overview. I would like to be able to access the MJPEG feed from within Loxone but can’t see any way to find the url of the mjpeg feed or how to authenticate it, if needed. I’m guessing that maybe I need to whitelist the Loxone mini server so that the IP address can be used to authenticate but I’m not sure.

So my questions are:

  1. Is it possible to directly access the MJPEG feed and what URL would I use?
  2. If I need to authenticate (within the URL) or whitelist the mini server how should I do that?
