Mobile: External PDF Viewer

Use case or problem

In the mobile app (at least Android) one can’t open the PDF file with an external viewer. However this is necessary because the Obsidian viewer can’t zoom in.

Proposed solution

Similar to the desktop version, after a long tap on the file in the menu there should be an option for opening the file with the default app.

Alternatively, always open it with the default app or make a setting for that, see Change default behaviour to be able to open links to pdf local files in default app by left clicking (instead of with an option displayed by right clicking).
