# This workflow demonstrates how to use the Compute Engine connector:
# Create and start a Compute Engine VM instance, then stop and delete the VM
# Each step waits until the long-running operation of stopping or starting the VM completes
# After each step, the machine status is verified
# Expected output: "SUCCESS"

  params: []
