I am writing this as im making a modpack that includes the sculkhordes mod but i ran into a small inconvenience that i have to trigger the horde by being next to the ancient sculk node in survival to start it, in my modpack im going change the mod's behavior slightlyso thought id ask if its possible to add a command that just triggers the horde, this way there is more flexibility for modpack creators if they wanna change how the sculk horde starts

This functionality does exist, you can use the /sculkhorde config command to edit the config ingame to enable automatic start. You can also edit the config file directly.
