It doesn't matter that everyone knows who she is. If you or her don't realize that randomly doing something that had been considered against company policy in Holo for years right after two high-profile graduations and returns in your company wouldn't stirr shit up, then you both live up to your name.How does this create drama? Everybody knows who she is already. If people dramafarming sperg about the secret-lite PL stuff in this current climate then they haven't been paying attention to every recent holo/niji graduation only putting the thinnest veneer of secrecy when they reincarnate. Also the only reason people can connect this to Kiara in the first place is because she decided to vaguely vent about something without giving any details, and retards took this very likely unrelated event and are dooming because they are retards.
If she isn't going to stream or do anything productive whatsoever aside from shilling merch, the least she can do is not make shit more stressful for her coworkers that actually care about growing their careers in hololive.
