I used to set "/lp group MyAdminGroup permission set *" to allow everything, but I've been told that it's a bad, so I checked the Nucleus permission list https://nucleuspowered.org/docs/permissions.html and it has a "suggested role" and it says that "The 'Suggested Role' column is also passed to permissions plugins", so, do I really need to set every single permission individually or is there a command to apply the suggested role to a group automatically?

The actual nucleus command to setup permissions is covered here in the nucleus docs:
