Change web callback button

I want customize the web callback button from the comercial module “Web Callback”

there’s someone who knows how to change the button?

At this time it can not be changed.

Is the button only created with onetime code or can I modify the callback ID? By this I mean if I create the button for website1 and put it on there. Then I create another button for website2, will this scenario work?

The reason for doing this is so that I can identify where the caller is calling from, website1 or website2

Yes you can create as many buttons as you want all with different destinations.
