How do I pay my credit card bills with Bull bitcoin?

I'm curious about the process of using Bull Bitcoin to pay my credit card bills. Could you please elaborate on the steps involved? Do I need to convert my bitcoins into fiat currency first? Or are there direct payment options available? Also, are there any fees associated with this payment method, and if so, how much should I expect? Furthermore, are there any limitations or restrictions I should be aware of before attempting to make such a payment? I'd appreciate a detailed explanation of the entire process to ensure I can make an informed decision.
