Hi Mahmoud,
We are really sorry to say that, we are not available to provide support for any kind of 3rd party plugin that has not included in our template, also that is not a part of our template.
In this issue, you need to hire someone else to customize the template to provide support the zopim live chat plugin in the template. After then you will able to use zopim live chat plugin in the template.
By the way, we have seen your 6 months FREE support was expired (http://prntscr.com/fa9560). Please be sure, you extend your support before asking more question for support.
Best Regards,
ThemeLooks Support Team
