Concentrate on your current task by enabling the Focus feature.
Tell Rambox to silence all notifications and sounds, so you can focus on your online meeting, your report, or your code.
You can find this option right next to your profile picture.
By default, notifications and sounds are enabled. If you toggle this option, Rambox will no longer send you notifications nor sounds of any kind until you toggle it back. Also, you can set this as a pomodoro timer, setting a time for it, and it will disable after it.
Also, you may want to check out the workspace's feature "Work hours".
Windows/Linux: ALT + Shift + D
Mac: Cmd + D
Keep in mind that no sounds will be played, even if you play a video inside your apps (i.e.: YouTube or WhatsApp video).
