Tracing how an automation was triggered

I have a few xiaomi zigbee buttons and I used Zigbee2mqtt to set one up as a panic button where it sends a “test” android notification to me when I press it three times (event shows up as triple). It worked as I planned and it remained untouched for about two weeks. Then a few days ago, I placed my cell phone near it and DEFINITELY did not click it (nor did I click it three times). I then received the “test” notification (within 15 minutes of placing my phone next to it).

How can I trace how this could have happened?
