Success	✅
Failed	:x:

Found issues:

• Pre-release publishing of a non-existent module publishes also minor, major & latest (latest even if the corresponding flag is disabled)

Other actions:

• Implement logic to determine if anything is published before the actual publishing steps to also visually show that a publish took place or not
