How to add line breaks in zoho.cliq.postToUser(...) message?

How to add line breaks in zoho.cliq.postToUser(...) message?

In a CRM function using Deluge I'm sending this message and attempting to add some line breaks but they are ignored.  Is there another way to add these breaks?

My message:
  • message: New urgent task\nDescription \nThis is a fake description.\n A new line?

The result in Cliq:
New urgent task\nDescription \nThis is a fake description.\n A new line?

(no line breaks)

Please advise.

Thanks
Clark
