Apologies if this has been asked elsewhere.
I see that we can provide basic color theme settings to blackbaud checkout. But when I call it from a custom giving form in my app, it launches a full window iframe that is solid white, and I can't figure out how to make this experience more integrated (such as a transparent background as featured in the screenshot from the docs page).
Is it possible? is it just demoing the 'optimized giving forms'…?
