API error message displayed to user during phone number verification

Describe the bug
When entering an OTP for phone number verification from the Profile section, a backend error message is shown to the user:
Unknown argument "otp" on field "Mutation.sendOtpToPhoneNumber".
This indicates that the API request payload does not match the backend schema, and the error is not being handled gracefully.

To Reproduce
Steps to reproduce the behavior:

Go to Profile.
Add a phone number and request OTP verification.
Enter the OTP.
Observe the error message displayed in grey over the OTP input area.
Expected behavior

The API request should accept the correct parameters and successfully verify the OTP.
If an error occurs, display a user-friendly message (e.g., "Invalid OTP, please try again.") instead of backend error text.

Start by reproducing the issue through Profile phone-number verification and inspect the request for the sendOtpToPhoneNumber mutation against the backend schema. Trace how the OTP response is rendered over the input area. Done means the request uses accepted parameters and backend errors are replaced with a user-friendly verification message.
