How to tell if background process is available

Hi, the Crystal watch face crashes on Fenix 3 because its API is 1.4 and the watch face uses background services. The thing is, without it, it only stops the weather, temperature location and my Tesla code from working. I commented out the following lines

            var lastTime = Bg.getLastTemporalEventTime();
            if (lastTime) {
               // Events scheduled for a time in the past trigger immediately.
               var nextTime = lastTime.add(new Time.Duration(5 * 60));
                Bg.registerForTemporalEvent(nextTime);
           } else {
                Bg.registerForTemporalEvent(Time.now());
           }

and the watch face works. I would like to put a that in an if block if the watch doesn't support background processes. Somebody know what I should look for?

Thanks.

First, see the sample here:

But here's the basics:

    function getInitialView() {
		//register for temporal events if they are supported
    	if(Toybox.System has :ServiceDelegate) {
    		canDoBG=true;
    		Background.registerForTemporalEvent(new Time.Duration(5 * 60));
    	} else {
    		Sys.println("****background not available on this device****");
    	}
        return [ new bgwfView() ];
    }
