Credit card cash back?

Alsalamalikum warahmat allah wabarakatuh, i wanted to ask about the cash back you get for example 2,3,4,5% when applying for a credit card :credit_card:. In crypto.com, you can apply for a credit card after holding some crypto money in crypto.com. Which allows you to apply for the credit card. It has some other benefits too. In the picture you can see approximately what i mean. My question is, this kind of cash back Halal or Haram?

Jazakumallah khairn
If there is any Proof available that would be great inSchAllah.
