Ability to add stages to the Amplify Console pipeline

I am trying to build dev, qa and prod environment.

> Changes to dev(git) will initiate the build and deployment process at its own.

Here, I need that if all goes good in dev then build and deploy qa and prod env also automatically (in. sequence, like if it passes qa then do it on prod )

I have 3 branches linked to 3 environment.
dev branch linked to dev environment
qa branch linked to qa environment
prod branch linked to prod environment.

There should be no manual interference while progressing with deployments in qa and prod

The entry point named is the Amplify Console pipeline, with separate dev, qa, and prod branches and environments. Start by reviewing the issue discussion and the existing pipeline behavior; done means deployments progress automatically from dev to qa to prod in sequence without manual intervention.
