Display and manipulate uploaded pdf

I am very new to bubble but I am trying to learn to make an application. I need some help creating an application to do some pretty specific things.

1.) upload files into my application (I know how to create this)
2.) the pdf files to display in my app from the uploaded files. (I want the user to see a PowerPoint in pdf form and be able to copy text from the pdf and paste it into a text element in the app)

I will need a step by step run down of how to do this as I am very new and I work in the healthcare field so programming is not my forte. Thank you in advance.

Very Respectfully,
