Adding comment to PDFs using Python?

Question

I am facing this task of adding comments to PDFs. Specifically, the task is to add a sticky note box at the beginning of the file and add a few lines of text in the stick note box.

I need to do this repetitively for bulk number of PDFs so I am hoping to do it programmatically in Python.

I've checked this SOF thread but it seems that it's asking a different question since it's adding text INTO the PDFs not in the comment.

You can add annotations to PDF documents with PyPDF2. The PDF format has several different kinds of annotations:

The AnnotationBuilder currently only supports free text annotations, but other annotation types will be supported soon
