Embed not working

My shortcode looks like this:

[slotti url=”https://slotti.fi/booking/kotineuvolakaari/” data-btn-theme=”dark” data-embed=”true” data-header=”none” data-margin=”none” ]

But I can’t get this working, all I get is a regular button (white background, orange icon and black text). The button itself works fine and redirects to the right appointment calendar.

I tried also on a site without Elementor. Any suggestions?

The page I need help with: [log in to see the link]
