[FEATURE REQUEST] Open downloaded PDF when clicking on it

Is your feature request related to a problem? Please describe.
I have several downloaded PDFs in my ownCloud. When I click on them in the file list a new screen opens. It contains:

• PDF icon
• File name
• File metadata like file type, size and date
• A snackbar with "file already downloaded"

Then I have to click on the overflow menu in the action bar and select "open with" to actually open the file in an external app.

Describe the solution you'd like
Open the file in an external app when clicking on it. This seems more useful to me then showing some metadata by default.

Additional context
As far as I remember my suggested behavior was implemented until it was removed about end of 2022, but I don't remember the exact version anymore.

The issue names no files, tests, or entry points. Start by tracing the downloaded PDF click behavior and the current metadata and “open with” flow in the Android app, then verify that clicking a downloaded PDF opens it in an external app rather than showing only metadata.
