The info about Deezer via https://support.sonos.com/en/services/deezer suggests that podcasts and live radio are available via Sonos. Indeed, the current notification about Radio France leaving TuneIn & Sonos Radio states that Radio France is available via Deezer. (https://status.sonos.com/)
The Deezer service has NO menu options for podcasts, or live radio - only music sources are available.
