Android app:// click action URLs not working

[loof2736]

🐞 Describe the bug

"app://" click action URLs don't seem to work, ie if I send a snapshot of my doorbell camera and set the click action to "app://com.mcu.reolink", tapping the notification does nothing

💻 Components impacted

Just the android client since the app:// link types are android specific I think
