Apple Music integration

I have various Bluesound devices in my household and use TIDAL because of the tight integration. A friend asked if this type of integration is possible with Apple Music, rather than having to AirPlay to compatible devices or (even worse) via Bluetooth. I didn’t think Apple permitted this sort of the access to any third party, but was told that Sonos does support it. If this is true, why can’t Bluesound do something similar?
