Volume bar is shown each time you connect to an audio channel

Our team is working on a multiplayer app for Oculus Quest 2.

The application has several rooms in which users communicate with each other (we use Agora Voice to connect users). Each room has its own audio channel.

Connection to the audio channel occurs at the moment when the user enters the scene.

After the latest Oculus Quest 2 update, a volume bar began to appear every time the user changed the audio channel. This greatly degrades the user experience.

Tell me, please, is there any way to remove the volume bar when changing the audio channel? Will this problem be solved with the next update of the headset?
I would be very grateful for your help!
