Android Question Capture hardware button press using an intent

I'm trying to capture a hardware SOS button to start a b4a app. I've attached the adb USB debugger to the device and got the following when I pressed the button:

B4X: 
02-05 17:42:57.972   944  1046 D SOS     : android.intent.action.SOS.down

I've created a new b4a app and have tried using a Service, Activity & Receiver to capture the button unsuccessfully, and I'm seeking advice on what else to try, please.

B4X: 
AddServiceText(SOSService,
<intent-filter>
    <action android:name="android.intent.action.SOS.down" />
</intent-filter>)

AddReceiverText(SOSIntent,
<intent-filter>
    <action android:name="android.intent.action.SOS.down" />
</intent-filter>)

AddActivityText(SOSActivity,
<intent-filter>
    <action android:name="android.intent.action.SOS.down" />
</intent-filter>)

It's a Ruggear 360, and it has a built-in app "LWP". I have requested more information from the manufacturer.

I have captured the log below, which includes the line
B4X: 
02-07 10:17:23.459   940   979 W BroadcastQueue: Background execution not allowed: receiving Intent { act=android.intent.action.SOS.down flg=0x10000030 (has extras) } to b4a.example/.sosintent
which makes me think my app isn't configured correctly?

The manufacturer has sent this information:

B4X: 
Please check from below about the boardcast intent:
Press: android.intent.action.SOS.down
Release: android.intent.action.SOS.up
Key String: KEYCODE_SOS
Key Value: 1079

If I use a foreground service, should the app be able to see the keypress and/or intent?
