I'm deploying a Bamboo plan with 4 different stages. The first stage detects whether trigger arrives from either DEV or PROD environments. If env is DEV, plan can run without problems. If env is PROD, I would need an approval step after first stage that pauses the plan build, sends a notification to admins and awaits for their approval.
How can I add this feature?
Environment permissions is the only way to go as in admins only have access to deploy to PROD. The 4-eyes approval flow you describe is not supported.
