There are three user roles that are relevant when using Conversations.
Agent is the user who responds to incoming messages and has conversations with customers. Agents have access to Workspace and All conversations. An agent can only view and work with conversations assigned to them.
Admin is the user who configures and sets up Engage. For Conversations, this includes configuring auto-routing and creating, for example, reply templates, tags, and notes used by agents. An admin also has the rights of an agent and dispatcher and can act as both. An admin has full access to all parts of the platform and is the only user role with access to Settings.
