Flow:

1. User initiates deposit: After pressing the Deposit/Withdraw CTAs, the user first sees the “Opening your wallet for signature” screen (Add "Opening your wallet for signature" screen to the Deposit and Withdraw flows #814)
2. Display Ledger modal: Ledger’s native modals then appear on top of this screen.
3. Transition to ‘Awaiting Transaction’: Once the Ledger modal is prompted, switch to the “Awaiting Transaction” screen while the user completes the signature.
4. Return to dapp: After signing with Ledger, the user returns to your dapp, where the “Awaiting Transaction” screen remains visible as needed.
5. Confirm deposit/withdraw: Once transaction is complete, display the “Deposit received” or "Withdrawal inititated" screens to confirm completion.
