Stand up for your needs. And deliver sufficiently that your manager prefers to keep you working. The one exception where I tried to work 100% in an open office led to me catching the flu and staying stick for 4 months. People complained about my coughing so they gave me a private office rather than allow me to WFH until I felt better (got to keep the private office though). I had no complaints, but just about no one is going to do that.
