So I’ve checked it and it seems PDF viewing isn’t supported out of the box..
I see three possible solutions here:
1. When trying to open URL with .pdf extension browser will open external OS app to view PDF file (meaning user will leave your Unity app)
2. When trying to open URL with .pdf extension browser will redirect users to Google Drive viewer page pointing to requested file
3. You have to embed pdf file using some JS PDF library, such as pdf.js
What do you think is best solution here?
I am inclined to go with 1.
