I get being disappointed in her (and personally I dislike her for being a Zionist), but I can also understand. Anything she does in terms of like malicious compliance is going to reflect on every trans person. There's also conservative congresswomen who I would not even want to use the same bathroom with, because they would absolutely go out and be like, "I felt threatened," or whatever. Every one of these people has a national platform and is extremely malicious.
I would be tempted in her position to hang out in the men's room doing femme things to make everyone uncomfortable. But I can't really expect her to be comfortable doing that. I hope she understands that they are going to keep pushing, and is just picking her battles and waiting for the right optics to take a stand, though I don't expect that's the case at all.
