Good morning, esteemed Zoho Desk community, warm greetings

Today I am here to raise the following problem, seeking a solution that I can implement: 

I need to implement an automation that allows me to send reminder messages to customers when I am waiting for their response after certain times: 24, 48 and 72 hours, as well as a ticket closure message when I do not receive a response from the customer after 96 hours.

I need to send those reminder messages through the ticket conversation thread in Zoho Desk (because every comment or response sent here also appears in the help desk that the customer can see, and it helps me with service tracking). This process is currently done manually by the company's agents, but we need to automate that task.

I know that with supervisor rules I can send emails to clients based on specific criteria; however, there's no option to send comments. As I mentioned before, I need these messages to appear in the ticket conversation thread.

We tried to create a workflow that would be triggered when a ticket's status was updated via a supervisor rule (but I was informed that this wasn't possible because it could create an automation execution loop). Based on this, we are reaching out to you so that you can use your expertise to help us implement this: whether by using Flow, custom functions with Deluge, or any other method that allows us to perform the update.

We thank you in advance for your attention and any ideas you may have.
