According to a article from 9to5Mac
Ray-Ban Meta glasses now feature Apple Music integration with voice controls
It’s been a while since Meta launched its own smart glasses in partnership with Ray-Ban,
Now those who own Ray-Ban Meta can enjoy deeper integration with Apple Music thanks to Meta’s latest update.
Using Apple Music with Ray-Ban Meta glasses
Since Ray-Ban Meta has built-in speakers, users can listen to music through them as if they were Bluetooth headphones. Of course, there was always the option of playing a song from Apple Music, but you had to do this manually by opening the Music app on your iPhone. Now this integration is becoming more seamless and intuitive.
With the update available for the glasses and also for the Meta View app (which lets you pair and manage Ray-Ban Meta), users can connect their Apple Music account directly to the smart glasses. As a result, you can control Apple Music without even having to touch your phone.
For instance, you can ask Meta’s virtual assistant using the command “Hey Meta” to play a song, playlist, album, station, or even artist. All hands-free while wearing the glasses. There’s also a new gesture that lets users touch and hold the stem of the glasses to play their personal station with songs recommended to them.
When you’re listening to a song, there’s also a new voice command to ask the glasses to tell you the name of the song that’s playing. Meta makes it clear that Apple Music login is done through the official API and credentials are not shared with third parties.
In a related update, firmware 4.0 of the Ray-Ban Meta glasses also makes them compatible with WhatsApp and Messenger, so you can use the glasses as a video camera.

Regarding to this question:
(In a related update, firmware 4.0 of the Ray-Ban Meta glasses also makes them compatible with WhatsApp and Messenger, so you can use the glasses as a video camera.)
Here’s the answer from Filipe
According to Meta, there's a new button in WhatsApp/Messenger when you start a video call from your phone. Press it and you can start using your Meta glasses as camera. Unfortunately, there's still no way to initiate the call from the glasses themselves – and it only works for video calls. Still, I hope this is just the beginning and that more integration will be added in the future.
