How to catch metadata of public radio webstreams

My HomeyPro 2023 mostly controls the background music in our home.

By playing a webstream-radiostation on sonos (homey-Sonos flowcard “play url” e.g. https://icecast.omroep.nl/radio2-sb-mp3)

The Sonos app on my Phone (not the Homey-Sonos app) always knows what song is playing by which artist … This is probably metadata somewhere in the webstream. Even the Zoneplay app, which I use from time to time catches this metadata.

But somehow the Homey Sonos app does not catch this metadata. The Sonos (flow-card)-fields ‘Track, ’Artist’ ‘Album’ etc stay empty… when I play a webstream (url).

How can I catch this metadata to Homey?

Anyone?
