Add Custom Button with Call activity to Leads view

Add Custom Button with Call activity to Leads view

Hi!

We use Zoho One.

I want to optimize time spend per sales rep when registring an activity on a lead. Today the process for a call (no phone system integrated with Zoho), that the sales rep opens the leads and clicks on +call.

I want to make a custom button with the same action (opening the window) direct in the leads view page. How do I do this? The idea is, that the same popup comes and you fill it out directly and save one pageload to the specific lead and scroll/click to the activity section.

Thanks
