Context menu "Share" does not work anymore

**Describe the bug**
The "Share" button in the context menu seems to have stopped working, but eventually this has come with an upgrade to Android 10. The "Export" still seems to work.

**To Reproduce**
- Open a vault
- Open the context menu of a stored item
- Tap the "Share" menu
- Nothing happens

**Expected behavior**
A list of apps should show up to share the file to.

**Smartphone (please complete the following information):**
- Device: Redmi Note 8 Pro
- OS: Android 10
- App Version: 1.0.2

**Additional context**
Reinstalling the app did not help.

Reproduce the context-menu Share action on Android 10 using the listed steps, then compare its behavior with the working Export action. Trace the Share entry point from the context menu; done means tapping Share opens the Android app chooser for the selected file.
