An email validation regex that is retrieved from the DexCare backend after signing in to the SDK. The backend services all use this shared regex from config for email validation. Failing to validate this regex will result in 400 errors from the services.
After this regex has been successfully retrieved from the server config, it is used in place of the EMAIL_VALIDATION_REGEX bundled with the SDK.
