Slack, writing, reacting and seeing unread

The Slack connector now writes, always with the app’s approval: post to a channel, reply in a thread, open a direct message or a group of 1 to 8 people, edit and react, with undo.

There are four action types approved separately: Send Slack messages, Start Slack conversations, Edit Slack messages and Slack reactions. It also reads what’s unread (capped at 100 and “100+”) without marking anything as read. An old connection keeps reading, but to write it asks for Reconnect in Customize → Connectors → Yours.
