We already have a Slack bot with custom automations implemented in other places. I’d like to create some integrations to Slack using the Slack Pack, mainly sending messages. Specifically, I’d like my messages to appear as coming from @CompanyBot, not @HenryHarrison. But I can’t figure out what I need to do during the authentication flow to make that happen. I can’t log in as @CompanyBot. So, is it possible?
