First, invite Howdy to your private channel by going to the channel you want to invite Howdy to and type:
and then run your meeting by typing:
@howdy run checkin @channel
You can schedule the meeting by typing:
@howdy schedule (script name) with (@channel)
Note: Due to how Slack works in private channels, you will need to type the exact phrase "@channel" (not something like @yourprivatechannel).
The @channel is critical for running meetings within a private channel of your choice.
