Does Using Swiggy HDFC Credit Card on HDFC Smartbuy gives 5 percent cashback on card and extra accelerated cashback as offered on smartbuy ?

Hi
I recently got my lyf Swiggy HDFC credit card. This is my 1st HDFC credit card and I am not at all acquainted with HDFC smartbuy portal.
When I open smartbuy portal I could see a lot of websites are giving 5 and 10 % cashback.
I just wanted to know wheather I will get these extra cashback in addition to my by default 5 percent cashback when I shop via smartbuy using Swiggy HDFC credit card?
A person working in HDFC BANK told me Swiggy HDFC credit card is not eligible for offers on smartbuy portal. Is this true?
