Screensaver will wait for your inactivity and automatically start when it detects system idle. If you are impatient you can start it manually to.
**** NOTE ****
Screensavers that install in your macOS Settings aren't supported on the App Store so after the purchase, screensaver will be visible inside Applications folder, not inside macOS Settings.
