How to hide the window of sonarworks when i start my iMac?

    Whenever I start my iMac, the SW's main interface will automatically appear on the desktop. I want to just start it automatically but hide the window.

    Someone told me :Please go to MacOS settings Users & Groups -> Login Items and check the Hide checkbox next to Systemwide.

    I certainly tried this way, but it didn't work. The window will still appear every time I start my iMac.Is there any other way?

    The version of my iMac is 10.14.1.

    Thanks.
