When users reach the bank transfer information screen (flow: Home → Transfer → Top-Up → Bank Transfer → Select Wallet/Amount → Banking Info), we should add a
button for email notifications.

Proposed Addition:

• Add a button labeled "Add Email for Notifications" on the banking information screen
• This button should navigate users to the existing add email flow in the account settings
• Position: Below the banking instructions, above or near the "Done" button
• Only show this button if the user hasn't already added an email address

User Flow:

1. User initiates bank transfer top-up
2. Sees banking information and instructions
3. If no email on account: Sees "Add Email for Notifications" button
4. Tapping button → Navigate to Account → Add Email flow
5. After adding email, return to banking info screen (or home)

Rationale:

• Users need a record of banking instructions for reference
• Email notification with transfer details reduces failed transfers
• Reduces support tickets from users who forgot transfer information
• Improves completion rate for bank transfers

Implementation Notes:

• Check if user has email: user.email or similar field
• Use existing navigation to account email flow
• Show inline message: "Get banking instructions sent to your email"
• After email added, auto-send the banking instructions

This would complement the push notification feature and ensure users have a permanent record of the transfer instructions.
