If you want to add a new button to the Jumbotron, you will have to go to Appearance > Editor then find the front-page-bottom-header.php file located in sections/front-page-bottom-header.php. Once, you find it then you can copy one of the button codes and paste it again in the file.
I would recommend that you use the following plugin to make a child them for the code changes and make a backup be for making the changes:
