I need help in setting up a script that works for my calling service

Please i need your guidance and expertise in how to go about a particular scripting.
You see, we are a call service that assists companies to receive calls for them, i need to create a system in my Zoho CRM whereby i will receive call from my already integrated CloudTalk to Zoho which my agents that when a call comes in, my agents will be able to see the contact information in a kind of script along with the call in the same page in my Zoho CRM and also edit the script and make adjustments to it instead of looking for the contact’s information on the contact list in my Zoho CRM.

Also, i want my agents to be able to use that script that will pop up when a new caller calls and easily assign the information on that script and then the script automatically sends in the information to the right database inside of the Zoho CRM
