I'm using Magento 2.3.5-p1 and I need to create a second bank transfer method the same as the default from magento, because the client need to be able to choose between bank transfer in 30 days or in 1 day with a 2% discount. I think there is no way to make that choice inside a payment method so I thought about creating one method for each option. I know I need to create a custom module but I don't know how to create a payment method the same as the default from magento.
Best regards, Rui Silva
