pop up in every zoho apps

pop up in every zoho apps

I am using zoho calender, books, crm, mail and chat at the same time in separate tabs in my browser (chrome).

I don't want each and every tab pops up when I chat when my staffs with zoho chat that is rather annoying.

Is there is way i can disable the pop ups in other zoho apps? I just want to chat inside zoho chat. 

thanks
