These are TwitchPress roles and capabilities being added in version 2.17, they act as permissions. Many capabilities won’t have any use without specific extensions. Some roles might be issued automatically.
Main Channel Editor
Custom Role: twitchpress_role_main_channel_editor
A channel editor isn’t automatically going to be a WordPress editor and vice-versa. You will need to issue capabilities in a more controlled manner. The purpose of these capabilities is to offer access within WordPress, to tools that access Twitch.

Custom Role: twitchpressdeveloper
This was the first custom role and capabilities – adding during the prototyping days of the project. The idea is for site owners to grant this permission to anyone they invite to do to work on their website, granting them special access to TwitchPress developer tools.
