Looking for Members
Pick the channel where LFM announcements are posted.
Pick a text channel and your members can advertise their temporary channel there with /lfm. Without a channel the command tells them that LFM isn't configured.
Where to find this?
Open the Dashboard, pick your server, open Generators and choose the generator. This is the Looking for members section of its page.
Horizon posts one message per channel, with the owner's name, their text and a link to the voice channel. A new post replaces the previous one of that channel, and the post is deleted once the channel is gone.
Pick the channel and press Set and save. Like the mod log, this applies immediately and isn't part of the unsaved-changes bar. Channels where Horizon is missing a permission are greyed out in the picker, with the missing permission listed.
Note
Horizon needs Send Messages and Embed Links in that channel. Owners can post again every 10 minutes.
