I need to show a unique ID for confirmation after filling in a form. But I don’t want use uuid(). On the form data I see the _id, question how can I use that ID to show on the form.

For example I can use the function uuid() to show the _uuid. What is the function for _id?

You cannot show the _id field from the form before submission of data because the _id number is generated at the server after submission of the instance.
