Diagnose issue adding private Slack channels

[ackernaut]

Bug

It seems that you can indeed add a private channel but that the UI view may look like it didn’t work. Also, the Slack auth view only mentions public channels

AC

• Users can add private channels. The Parabol UI updates correctly to show the added channel.
• Do we have the option to configure the Slack auth view so that it allows and states the ability to add both private and public channels?
• It looks like the channel name loses the first character? t_exco_talent becomes _exco_talent?

Although I can select the private channel when adding the app, I cannot find (or search for) it when going to the Team Notifications drop-down.

So, I guess push notifications don't work for private channels.

Notes: push notifications don't seem to work for private channels. Steps to reproduce - connect slack integration > add a private channel > start a new meeting. The notification is pushed to the Parabol app on slack but not to the private channel, the UI also shows notifications set to go to @ Parabol instead of the selected channel

Integration with Slack doesn’t work if it’s a private channel
