Revised language for "Instructional team communication" section of online teaching recommendations

Current recommendation text:

The instructional team should have a chat channel separate from the main classroom chat to discuss logistical needs or private concerns. This should be something with manageable notifications that is private to just the team. A platform like Slack (using a private channel or group direct messaging) or a WhatsApp group can be effective with this.

Suggested new text:

The instructional team should have a chat channel separate from the main classroom chat to discuss logistical needs or private concerns. This should be something with manageable notifications that is private to just the team. We recommend creating a group direct message on Slack, within The Carpentries workspace, which anyone can join through this invitation.
