Manual testing steps

1. Go to Test dapp
2. In the section PPOM - Malicious Transactions and Signatures click on all Signatures
3. A banner should appear once you try to confirm the confirm modal so the users can acknowledge the risk and confirm or reject.

Transaction scenario
Transactions are using the old banner alert so it should work as before.
