DocType Timeline info - Add additional info

Every DocType has a Timeline under it like:

I want to added additional information like: modified_at , modified_by.

I can’t locale the files that render the above ‘Created’ so to overide it with my new info.

try

frappe.ui.form.on("YOUR DOC TYPE", {
    refresh: function(frm) {
       frm.timeline.insert_comment("Submitted", "Your Comment");
    }
});

Ty for your answer, you gave me a head start :slight_smile:
