WatchOS Haptic Feedback Without Sound

Id like to provide haptic feedback to users on Apple Watch without playing any sound (for my meditation app). The only way I found to play haptic feedback is

WKInterfaceDevice.current()play(.start)

but this produce sound as well. Apple's Mindfulness app has haptic feedback without playing any sound. Is there a way how to achieve it? Thanks!

This is an old idea but perhaps it still works?
