Choose where new channels created by a certain primary channel get their permissions from. You can use this to allow only certain people to create channels, but anyone to join them.
Available options are:
parent: (default) New channels will use the same permissions as the "+ New session" channel they are created from.
category: New channels will use whatever permissions are set up for the category they are in (the same behavior as creating channels manually).
CHANNEL_ID: Specify an existing voice channel whose permissions new channels will copy. Must be a permanent channel that the bot can see - if the channel is ever deleted or becomes inaccessible, the primary channel's permissions will silently be used instead (as is the default).
