Can I Anonymously Attend A Jury Trial?

Location: Wisconsin, US

A man who stalked me for many years has an upcoming jury trial. Class E felony stalking, victim is someone I don't know.

He used to insist he knew my name, but I am sure he's lying. If I show up to his trial, could I be required to say my name? If yes, can I do so in a way where he doesn't hear/see it (e.g. show my ID to the judge/ADA)? And if no to that, can I just say no thanks and leave?

I would not anticipate there being anyone at the trial beyond the guy, his PD, prosecution/judge/staff, jury, victim, and victim's attorney.

If relevant, context of him stalking me without knowing my name: I gave him my number when we chatted on a normal dating site years ago, back in the time when you used a username on the sites, not a real name. I stopped responding shortly after, as there were major red flags, and he went absolutely nuts. He just constantly made new phone numbers and Venmo/paypal accounts and called/texted/sent me $1 with a creepy message for years and years. I have a list of maybe 40 phone numbers he's used over the years. He made multiple defaming websites about the victims whose names he knew, so I assume I'd have gotten similar treatment if he actually knew mine.

He shows no remorse, doesn't think anything he did is wrong, and now seems to legitimately think all his victims were hired by the government to falsely accuse him because of his political views (he's gone off a very far-right deep end since he went to jail around seven years ago).

I want to witness this guy finally (hopefully) getting what he deserves for over a decade of harassing multiple women, but not if it could end up causing significant trouble for myself. Thanks.
