I'll modify the verification flow to verify Mobile first, then WhatsApp, and finally Email:

I've reordered the verification flow to match your requirements:

1. Mobile Verification First: Users will now start by verifying their phone number
2. WhatsApp Verification Second: After verifying their phone, users will verify the same number via WhatsApp
3. Email Verification Last: The final verification step will be email

Changes Made:

1. Reordered the verification steps in the main component
2. Updated the progress indicator labels to reflect the new order
3. Added a back button to the email verification component
4. Made the back button optional for the phone verification (since it's now the first step)

The flow now follows a logical progression where the phone number is verified first, then that same number is used for WhatsApp verification, and finally email verification is completed.

This approach aligns with common mobile-first verification practices where phone verification is prioritized as it's often considered more secure for initial identity verification 12.
