Desktop notifications not working on Arch Linux

### Description

I'm not getting any desktop notifications. I'm using Bspwm window manager on Arch Linux. The Element window is in a specific workspace. I don't get notifications whether I'm in that workspace or another workspace.

I don't know from which version it stopped showing notifications, but in the past I would get them, but not always(a hit and miss behavior).

### Steps to reproduce

- Open Element desktop in a workspace
- Receive a message in a one-to-one chat room or get mentioned(in an IRC channel)

There is no desktop notifications.

I only notice a marker in the Element tray icon while receiving a message in a one-to-one chat. I don't think I ever got that tray icon marker while getting mentioned in an IRC channel.
