None of your three steps are required to run un-signed apps on macOS. I am happily running many unsigned apps with SIP still on. All that is necessary is to approve the app in the security pane of the System Preferences. Not even a reboot needed.
The real steps:
1) try to run unsigned app.. get an error
2) launch system settings, go to security page. Approve the recently denied app (will probably need your login password)
3) launch the app again.
This is well documented.
