Narrative text in viewport

Is there a way to style the placement of the narrative panel in NeatLine? I can affect its design, but I can’t seem to change where it exists relative to the viewport.

Alternatively, is there a way to get it to appear as part of the viewport? Or a way to mimic the NeatLine Text plugin “zoom in on this record when clicked” functionality?

Our interest in this stems from the navigation of the Digital Declaration NeatLine exhibit.
