To resolve this issue, we need to request a new permission. However, this is high-level permission and primarily intended for file manager apps.

MANAGE_EXTERNAL_STORAGE
...Intended to be used by few apps that need to manage files on behalf of the users.

We do not actually require this permission as we can tap the button on the top and access files through the system's file picker using an intent. In our app, though, we will not be able to display file thumbnails on newer APIs due to Google's privacy concerns.

I am sharing a video to demonstrate how we can upload a pdf file from the device and I'm closing this issue.
