I now sign my name on the white paper, take a photo and stick it in that position in the form of a picture.

Generally speaking, if you need to use the electronic signature of the paper, you can generally ask the tutor to write a signature on your paper, and then take this signature in the form of a picture and send it to you in the form of a picture. First, take a photo of the handwritten signature and save it as a picture file, and then insert it into the signature of the paper.
