How can I use my android tablet (along with stylus pen) as external display on linux (Ubuntu 20)

I am running Ubuntu 20 on my ASUS VivoBook laptop. I have many PDF files (of research papers) that I often read and annotate. At present, I transfer the files to my S6 Lite tablet (an android tablet) to read and annotate the files there using the stylus pen S-pen. However, this creates multiple copies of files, which are harder for me to find and maintain in the long run. I was wondering if I could directly annotate the files in the laptop by using the android tablet and its stylus pen. The laptop itself doesn't have touchscreen. Is there a way to use the tablet as an external monitor for the laptop and use the S-pen to annotate the PDF files on the laptop?
