Hey Harry,
You’re in luck - the Button Bar component just launched so instead of using the HTML you built, you would be able to use the Button Bar component in order to mimic the same look and UX.
For the Links to render/open in each button component (Left/Right), just point them to their corresponding URL’s in your sheet OR by adding them in the “Custom” field inside the Glide Editor.
You would then just add a Text Component underneath the Button Bar component for your Copyright info.
Cheers.
