Hi, there are several online platforms which allow adding text to pdf in the form of watermarks, as plain text or as an image. I recommend a *.png image since you mentioned the text will always be the same. I've also tried PDFCandy (https://pdfcandy.com/add-watermark.html), which is great if what you need is to add a watermark. You can determine the position of the watermark in the document. It's an easy online tool which doesn't require subscription or downloading, although you do have that option. I'm attaching the generated pdf.
