Activate Zscaler using AppleScript

I am trying to open (bring to foreground) Zscaler client at a specific time using AppleScript so that I don’t have to click “Open” button everytime.
tell application “Zscaler” to activate

The script itself runs without any errors but fails to bring Zscaler to foreground. I think this is because Zscaler client app is un-scriptable.

I am using Automator on OS X 10.15.4.

Looking forward to receiving a tip.

Thank you.
