Question about Slack Integration and Assignments


So I have a Slack integration with Sentry. It works great, and I was wondering since in Sentry you can assign issues to people, if given a mapping of e-mails and Slack usernames and channels, the Slack integration could message users or channels upon being assigned.

Is this possible? I currently am stumped trying to figure it out from the configuration window. Apologies if this is documented elsewhere.
