Themed icons for Android 13

Use case or problem

Obsidian was one of the few apps to have a themed icon when I was on Android 12.

It however doesn’t appear to have a themed icon after upgrading to Android 13.

Proposed solution

It’s possible that Android 13 requires a different implementation for themed icons.

Here is Tasks’ implementation for the same:
Monochrome icons

After this, they have a working themed icon in Android 13, as seen in the screenshot above.

We didn’t do anything to support themed icons in Android 12 nor did anything for Android 13.

Would it be possible to do though?
