Ah, that makes sense. Well the layout itself can accomodate that kind of information as it is already composed of a title and description. So I would add a “type” field to make it clear, besides the icon, what kind of backend each access means. See the image below.
Now, regarding making one of these configurations, perhaps the onboarding can start a process in which the admin users will config as many backends as they wish and what the default config should be. Here we could point to a demo config as well, for testing purposes.
