How do I get rid of the Notification Center button in the menu bar in High Sierra?
It's that one in the far right:
I'd like the space it occupies to disappear too. Apparently it used to be possible to hide the icon but the space would remain.
Also, I want to continue using the Notification Center; currently I access it with a gesture on my trackpad.
The answers to Remove the Notification Center icon from the Menu Bar do not work for me in High Sierra.

launchctlcommand, then re-enable SIP. Does thelaunchctlcommand not disable the icon from appearing? – IconDaemon Nov 23 '17 at 17:52launchctl unloadjust stopped notification centre from working but left the icon untouched. I want notification centre to work, and I want to hide the icon. The answer basically does the opposite of what i want. – minseong Nov 23 '17 at 17:55
