Apps in Slack may include functions, which allow workflows to connect with services outside of Slack. While app developers set permissions to determine who can use any functions their app includes, admins can further restrict access if they'd like.
Note: It’s not currently possible to add functions to workflows created with Workflow Builder. To manage which functions are available when this feature is released, admins can restrict access now.
Restrict access to functions
Owners and admins can restrict access to functions to determine which members of their workspace or Enterprise Grid organization can add them to workflows they create.
