Can I use droplets in popup notifications?

In the main page I have a popup notification with information on [daily/weekly] novelties. It contains a piece of html (see https://www.aiace-italia.eu/). Can this be managed by droplets? Are droplets strictly requiring Foundry stacks?
Thanks for your attention,
Franco

I’ve got Embeds and Droplets in non-Foundry pop ups, no problem. Give it a try!
