Updating data in Zoho CRM


I need help with updating the data about leads in Zoho CRM.

  1. I scrap data from Linkedin via Linkedhelper tool and transfer it via Integromat/Make to Zoho CRM

  2. as a next step, Linkedhelper tool sends the message to the lead, and then if the lead replies to the message I need to add this information to the Zoho, but I can not understand how to make it:
    a. Find the current lead in Zoho, which I had added previously at the beginning of the campaign (at the previous step)
    b. Update the field in the Lead section

Can anyone help me out with this issue?

Would it be possible to share a screenshot or a Loom video with revealing any sensitive information?
