invisibly
In hidden fashion
In a way that cannot be seen.
Something happens invisibly when it occurs without being visible or noticed: The software runs invisibly in the background.
The word often suggests subtlety or concealment—changes that happen invisibly may go undetected until their effects become apparent: Power shifted invisibly from one faction to another.
