How can I force an app providing me with (haptic) notifications when my watch is in sleep mode?

I tried inserting the app in the list of apps excluded from muting in focus settings in my iPhone both in DoNotDisturb and in Sleep, enabled syncing across devices. However when the notification comes, it only appears on my iPhone screen and my watch being in Sleep Focus remains dark.

What I want to do is exclude HomeKit from muting so that I can get activity notifications from my security cameras even when I am asleep, in the same way I get alarms with haptic notifications on my wrist.
