Random Content Feed

Hi,

Great plugin-in. Been using it for months now and works great.

I would like to show a feed of my post types. I try something like this but I keep getting all the articles of my site rather than just the random content post types:

https://example.com/feed/?post_type=random-content

or

https://example.com/feed/?post_type=endo_wrc_cpt

I also need the filtering by group like this:

https://example.com/feed/?post_type=endo_wrc_cpt&group=xxx
Any idea ?
