Podcasts on Fitbit Sense

Hi

how do I listen to Deezer podcasts on my Fitbit Sense? I have added podcasts to my favourites on my Deezer app, and tried downloading episodes, but nothing is registering on my Fitbit. Both the Fitbit and the Deezer websites say that it is possible to listen to podcasts via Deezer on a Fitbit Sense, so please can you explain how to do this?

I subscribed to Deezer Premium and bought a new Fitbit especially for this purpose, so please help.

thanks.
