Using UPI handle for the first time

[CyberPsych]

Can Myntra check whether I have used MobiKwik UPI handle before, if I am completely new to Myntra app/website?

Question arises because of the 3rd point here. It says users should be new to MobiKwik UPI.

yes, they have full payment history.. which cards used, which payment methods already tried etc.

No, I am asking whether they could find if I used the MobiKwik UPI handle outside of Myntra app.
