How do I ask for a new work coach?

I’ve had the same work coach for 4 month but 2 weeks ago I had an appointment with a new one and same today. I’d gotten used to the old one as she was nice and seemed to have some understanding of the current job market, but this new one is very passive aggressive and somewhat sarcastic, making everything I do or have done feel wrong or like it wasn’t to her standards, it’s like she’s trying to catch me out even though the only reason I’m on UC is because I literally can’t land a job. Anyhow how do I request a new work coach?
