ALLOWmode: Uses theallowModslist to specify what mods players are allowed to have. Any mods outside this list will result in a failed check. Having less mods than the list is allowed.DENYmode: Uses thedenyModslist to specify what mods players are not allowed to have. Using any mods in this list will result in a failed check.STRICTmode (default): Uses therequiredModslist to specify what mods players must have installed. Not having all the mods in this list will result in a failed check. You can allow players to have any extra mods in their modpack withallowExtra
