What counts as "unattended"

Question is for the force power [detonate](https://swse.fandom.com/wiki/Detonate). It says "One unattended object within 12 squares of you and in your line of sight." Now unattended can be interpreted differently, so what would you say is unattended? for example, a power pack on someones utility belt? A pistol in its holster? A drinking glass in someones hand, and that person is in conversation and not aware of the force power?

Essentially, what would you call unattended because this could be a very useful utility power for distractions or damaging critical objects and some clarification from the community would be great. Any insight would be helpful for future reference.
