To export your meeting notes to Slack, click on the button in the upper right to End Meeting (during the meeting) or Send or Export Summary (after the meeting).
You'll see a menu of options for sharing your meeting notes.
Select Post to Slack.
If this is the first time you're exporting to Slack, you'll prompted to authorize your Slack account. For future exports, your Slack account will be authorized and you'll skip this step.
Once you've authorized your Slack account, choose the channel, group or individual you want to post the meeting notes to, and add a message if you'd like.
Click the green "Post" button and your done! Your colleague(s) will receive your message in the Slack channel you selected with a link back to review the meeting notes and action items in WorkLife.
