Hey Douglas,
Thanks for reaching out to us!
There are a couple of options that you can pursue for setting this up. If you would like to dig into the code for adding the necessary capabilities to new roles, you can take advantage of the “capability_type” that we add to each of the Events, Venues, and Organizers custom post type. You can see where the post type registration begins here and see the capability types for each of the custom post types.
Alternatively, you could use a third-party capability management plugin to quickly and easily create new user groups and give them the necessary access for adding/editing those different plugins.
Let me know if this helps.
Thanks!here
