I'm building a public-facing story map using sidecar blocks with media action buttons to focus the map on particular map extents. The media action button appears as a thin border around some text and the page background colour, making it not obvious it's a button. It's also impractical to type the instructions inside the button.
How can I format media action buttons in a sidecar to make it more obvious, or at least match the format set in the theme for a basic button? Why does the media action button not take on the button format as set in the theme?
Thanks,
