Vercel's Slack integration now includes Comments. Once the Vercel Slack app is installed, you can subscribe to messages in a channel about all Comments made on your team's deployments or Comments made on specific projects.
If you configured the Slack app before October 4th, 2023, the updated app requires new permissions. You must reconfigure the app to subscribe to new Comment threads and link new channels.
You will get a Slack message for each new Comment, and replies in Slack will automatically appear in the Comment thread on your deployment. You can also log in to the integration with your Vercel account to get DMs about comments relevant to you.
