Zoho Scripts blocks rendering of the page

Zoho Scripts blocks rendering of the page

Hi there,

Here are the files causing my page to load slowly:
css.zohostatic.com  and bizappln.zohobookings.com

How to make this script to load without blocking the rendering of the page?
I have attached a screenshot for your reference.

I'd be happy if you assist me and solve this issue ASAP.

Thanks & Regards,
Bala.
