1- As I have marked in the image with a red box, I want to display a desired text in this section
For example, when the user chooses to pay by check, display a text stating what conditions the check should have... And when he chooses another payment method, another desired text will be displayed
2- How to control a payment gateway?
For example, if the check payment method can be controlled and accessed with 'check', how can the other public and private payment methods be accessed and controlled? That is, where and how to get their name (eg 'check')?
If a site has 3 payment methods Check method Method A Method B How to access these three payment methods? By choosing each one, a specific task can be done
