Install Agent Designer if it is missing
The Agent Designer is included in the 27.4 monthly update and automatically installs in upgraded sandboxes but not production environments. When copying a post-v27.4 production environment to a sandbox, you can manually install the Agent Designer using a specific AppSource URL with its app ID.
