edit: I believe scrcpy fits what I looking for right now, although it views black screen for some materials (during navigation) it does give me a good view of the pdf. I doubt if I would be able to download the pdf unfortunately, but hey, this is the next best thing. Since I would need to login first, I might use Shizuka as suggested by the first commenter (not mentioned username incase they decide to delete acc someday).

I am willing to provide any information one could need to help me with this, so when I was getting my admit, the people concerned with this app told me I would be getting Pdfs of notes prepared by the faculty and videos too. Honestly, I know how to pirate those videos so that I can use them at any time, but since I don’t have a phone, I can’t view the content which is not available on website [pdf notes] and only available for view on android and it’s view protected and the freaking phone is small and I can’t hope to read from my phone [and they know that].

So, I was thinking if it was possible to break the protection which can allow me to view the notes on my linux laptop using some app. Or better yet, pirate the bloody pdf so I can take their print outs and read it in physical form. Please ask me any further info you might need.
