I need to have some demo phone numbers like 9999999999 for testing but do not want to trigger an otp sms. is there a way to add these numbers in auth? self host v1.4.13

TL;DR

The user wants to know if there is a way to use demo mobile numbers for testing without triggering an OTP SMS. They mention using `http://request-catcher:5000/mock-sms` for testing and suggest using `_APP_SMS_PROVIDER=user:password@mock` in the code. However, this does not work for them and they have created a feature request on GitHub. No solution is provided in the thread.
