How to check storage rules?

To view your existing Rules, use either the CLI or the console. Make sure you edit your rules using the same method, consistently, to avoid mistakenly overwriting updates. If you're not sure whether your locally defined rules reflect the most recent updates, the console always shows the most recently deployed version of your Security Rules.

To access your rules from the Firebase console, select your project, then in the left-hand navigation panel, click Storage. Click Rules once you're in the correct database or storage bucket.

To access your rules from the Firebase CLI, go to the rules file noted in your firebase.json file.
