Volume control hardware keys doesn't work on chrome on android

I’m developing a web app using lib-jitsi-meet.
When client start using video and microphone in chrome for Android, he can no longer control the receive volume with the hardware keys.
This occurs when echo cancellation is enabled.
Specifically, the audio received by webRTC is controlled by media volume, but the volume hardware key controls call volume.

The expected behavior is that even with echo cancellation enabled and video and microphone, the hardware key will control media volume

Any ideas on how to fix this?
