How to add a discount on user first order

This feature is used to allow any logged-in user to add a first-time discount on their first order.

For eg.: If users register the first time and place the first order with their user login and password then allow a flat discount on the order.

With the same user and password if they place an order next time with the same products or different they are unable to get the discount on that order.

Let's see the example screenshot with the settings to get more ideas about it.

Once users place the same order more than one time then no discount will apply.
