Solved Rename buttons (avoid having repeated names)

Hello
I am not a great expert in CSS or code, but I need help with the following:
It turns out that when I create a page in Divi, for example, with several calls to action, all the buttons end up calling themselves the same: et_pb_button et_pb_custom_button_icon et_pb_promo_button (I realize this when opening in Google Chrome, right click, inspect)

What I need is to be able to change the name of each of the buttons. First, to make them easier to identify. Second, because I want to create different labels for each of the buttons in Google Tag Manager and if they have the same name, I cannot identify and separate the actions that are performed on each button.
Is there a solution that can be implemented, for example in the "advanced" tab of each module?

 

I guess I need more information.
I took one of the 3 blocks that I have in a call to action.
To one of them, I included in the Advanced tab a CSS ID, which I called BOTON_CENTRAL.

Then, what happens to me is that the class that I have to copy to use in Google Tag Manager, is still et_pb_button et_pb_custom_button_icon et_pb_promo_button, which is the same for the 3 buttons of the 3 blocks that I have in my call to action.

I would like:
1. Change the class of the button so that it does not continue to be called et_pb_button et_pb_custom_button_icon et_pb_promo_button, but a name that I want to give it.

2. If it is not possible, what is the syntax I should use in Google Tag Manager, to refer to that button exclusively and not to a group of buttons that are called the same throughout my website

Here is an image that can help explain what I need:

 

Thank you!!!
