Retrieve button id and include as mailtag

Hello,

i hope someone will help me somehow.

1. I have a table with 3 columns (20 such tables on the site). Each column is specific device description.
2. At the last cell of the column i have a button which calls the elementor popup with cf7 form
3. The form is the same for each button.

All we need just ad as mailtag something that will say as from what column form was filled to know which product is choosen. I understand that i can add for each button specific class or id to differentiate them. Also I understand that I can retrieve the button id/class with get.element.by id.

But I can’t get it, how i can sent this info as mail (as mailtag). Creating as many forms as buttons there are not a solution. There are about 60 such buttons.

Can you please give me at least some recommendations where to look?
