I am using the developer account to develop a POC for e-signing using Docusign SDK. Our App authorises users using phone number and hence at the E-sign process for a loggedIn user, we need to ensure the authenticity/Identity of the user is correct. I’ve configured the template to enable the identification of user via phone/sms but during the signing docusign app is not asking for any OTP. Please help.

I’ve referred this link for the configuration.
