There is a requirement where we are writing a custom function to send an email notification to the client if no activity happened on the ticket since the 7th day or the 10th day after the status changed from A to B.

For the same, I am writing a function and using API https://desk.zoho.com/DeskAPIDocument#Tickets_Listalltickets
but here we don't have a field that can help to fetch the date/time from status "with agent" to "pending client".
or any status to any other status.

Is there any relevant field available that I can use for this requirement or can we add it to the application
example a field required like statusChnagedTime
