Extract email address from JSON payload string possible?

Extract email address from JSON payload string possible?

Hi Support,

Current Functionality
I have a flow that receives information via a JSON webhook POST and then updates/creates records using this information in Zoho CRM.

What I Want
An example of the JSON payload data which is received looks like the below image:
JSON Payload

I want to be able to extract the email address from the Comments and place it into a specific field (or any other alternative as long as I can extrat the email address). Is there a way to do this? Maybe a script that can extract all the text between the commas (,) which have an "@" sign?

Let me knwo what is possible and thanks.
