Pay with Debit or Credit Card - The button is not displayed

Here is a tutorial: https://www.codexworld.com/paypal-standard-payment-gateway-integration-php/ Below is a button. If I click the paypal gate will appear. There is also a button: "Pay with Debit or Credit Card" When I write a code according to the tutorial, I do not have a paypal button on the sandbox: "Pay with Debit or Credit Card" I only have the button: "Create an Account" Where is the problem?
