Zscaler not opening in big sur 11.4

Hi I recently installed zscaler 2.2.4 version in big sur 11.4 mac os. the application got installed and when i try to open it is not opening.

I also don’t see the application in menu bar as well. I tried to search for system requirements for zscaler and i’m not seeing much information on it. please advice what version of zscaler will work with big sur 11.4 version. thanks.
