To enable overlays:

# Overlays
DEVICE_PACKAGE_OVERLAYS += \
    $(LOCAL_PATH)/overlay-lineage

Tests

• Ensure section is not visible by default
• Ensure section and option are visible when an app registers org.lineageos.settings.device.HARDWARE_SWITCH_SETTINGS
• Ensure pressing on option opens the custom fragment defined on device-side (or external app) when it registers org.lineageos.settings.device.HARDWARE_SWITCH_SETTINGS
