To run workflows, a user must have at least Operator level permissions.
Run a workflow from Relay's web interface, or use the CLI.
To run a workflow from the web app, navigate to the workflow's page and click the Run button in the top right. Relay will prompt you for any required parameters and then launch the run.
Log in from the command line, then run a workflow by specifying its name and any required parameters:
relay auth login firstname.lastname@example.org relay workflow run hello-world -p message="Hello"
