You can paste the whole code snippet Firebase gives you (imports and all) — it'll pick out the config automatically. Paste the exact same config on every device (phone, laptop, staff devices) to keep them in sync. The config itself isn't secret — real access control comes from sign-in plus the Firestore security rules you set up in the console.
