How do i get my first credit card??🥲

Hey people here is my cibil score.

749 cibil(not new been here for 1-2 years)

I had my first credit card(slice) 1 year ago but they stopped their credit card service so i was cradless again..

I'm 21 yeo director in my family business. Have 1 car loan on me(20L) and 2 business loan.

Still I'm getting rejected for amazon icici credit card?? Or any other LTF credit card?? Why is that...

Few months back i got offer for swiggy card but didn't take as it wasn't LTF but now that it is LTF they rejected it.

Can someone help me??
