How can one add custom CSS to the **Pop-up Sidebar** component? I don’t see anywhere to add custom css like the other sections / components? Am I missing something?

Hi @Mark_Pederson 👋

Indeed you’ll need to add the custom CSS to the `Menu` container inside the section. The Pop-up Sidebar section is focused on handling the interaction effects of the popup.

May I ask what custom CSS you wanted to add?

This will help us figure out if it’s something we should add to the section or if it’s something you can achieve with custom CSS on the `Menu` container.

I’d like the background to be blurred too. How did you do it? I just can’t find any setting or custom CSS for it!
