Triggers in Rule Machine refer to events, not states/conditions. The only way to test them is to make the event happen. 
So, in your case, I suppose that would be arriving home (though if you just want to test the actions, either "Run Actions" or adding a virtual device or something more easily within your control as an additional trigger would also work).
But now that you say that: if you're usuing the mobile app for presence, and you think it's not sending the events to trigger your rule, that could very well be! This tends to be unreliable for a lot of people. There are a few options for getting presence into Hubitat, and here is a recent post where a user compared several of them:
Note that the mobile app isn't even on their--maybe he found it too unreliable? I don't know (just guessing). But one of those options may work better for you. Some can be done with native Hubitat drivers and just a different mobile app, while others require something extra (like the HomeKit option I use, which needs a HomeBridge "server" and a HomeKit hub of some kind, like a HomePod or Apple TV). There are also more options not on that list.
Not ideal, but at least it works better!
