Web Player info?

Has anybody got an idea how to get the info button with the web player 5 as it is on this podlove-page?
I just noticed that my “Zusammenfassung” and “Untertitel” aren’t visible anymore since I upgraded my website from 5.6 to PHP 7.4, since the web player didn’t run anymore.
I’d be thankful for any ideas :wink:
Best, Nils
