Maximizing Cashback on HDFC Swiggy Card for Utility Bills & Repayments Tips?

[Thunder_god16]

Just got my LTF HDFC Swiggy credit card Via Cashkaro along with 1000rs reward. Looking for the best ways to maximize cashback on utility bill payments and card repayments. Is it more beneficial to use the PayZapp app for these?
Any tips on maximizing rewards would be appreciated
