[If you're going to say that someone was tied up, you'll need some evidence to back up your case.] While it's true that she could have... would she even know how to activate it? It's not like the descriptions that the store gives comes with an instruction manual.

Unless Tamamo-san somehow explained to her every last detail on its activation? Do you think she would do that?
