Currently it's only possible to connect a single directory/environment of Slack or MS teams with Atlassian Assist. You cannot have more than one Slack systems connect to the integration, or have Slack and MS teams connected at the same time.

Companies have multiple projects and it would be great to have the ability for them to connect a different directory to each project, or even have 2+ connected to the same project, as they have different systems for their customers.
