No. I base this on two facts from the manga.

One, she was shown using it just by glancing in the direction she wanted to make explode. In Vollstandig, its quite visible, but that's the nature of the release. It makes them into orbs.

Prior to that, however, she was shown using it with her eyes, when she explained her abilities. She made a wall explode at the Wandenreich palace without moving an inch (in fact she had her hands on her hat at the time), and she caused an explosion behind her, while she was talking to people in front of her.

Secondly, Reishi is rarely visible. Only when acted on by a Vollstandig, or gathered in extreme amounts is it visible. Prior to using her Vollstandig in the manga, her Reishi was never shown entering anything. That's because it was motionless. Invisible. She will it to happen and it did. That's what makes her deadly.

Hope that answers your questions.
