TruecallerSdkScope#SDK_OPTION_WITH_OTPis selected while initialising the SDK to provision for the verification of non-Truecaller users also.
TruecallerSdkScope#SDK_OPTION_WITH_OTPis selected. This will be called when the user is not a Truecaller app user. Also, you'll get a Nullable TrueError only when TC app is installed and user is logged in. For other cases, it would be null. This optional TrueError can be used to determine the user action that led to initiating manual verification. So using this TrueError, you can get to whether the user pressed on the footer CTA on the verification screen OR the system back button.
