Usually, you hide excessive items from the status bar like this:

1. Holding ⌘ [CMD], drag it away from your menu bar until you see a ✖️ (cross icon)
2. Let it go

To recover the icon, simply reopen the app when it's already running (in most third-party applications)

But in some cases^*, unwanted icons can't be hidden like that. At this moment barhide appears.

^* like Magnet, or Spotlight and Notification Center prior to Big Sur
