You can add that using a HTML module.
1. Go to the page you want to add the HTML to.
2. Click page builder 2.0 at the very top of the page to activate the page builder.
3. At the top left you’ll see a +. Click that and a tab will open showing all sorts of things you can add to the page.
4. Look for HTML. Click and drag it onto the page (click and hold your mouse button down to drag it. Release your mouse button to drop it.) as you move it around the page you’ll see a blue box that shows where the HTML will be placed if dropped at that time. When that blue box is where you want it release your mouse button to drop it.
The settings will open for the HTML module. Past in the HTML code.
When you’re done save the HTML module then at the top right click done then publish.
