Frosted film is one way to go but there are other privacy options for windows too. I decided to check window films
https://windowtechcanada.ca/security-film/ when I was figuring out what to do with mine and they had different types available. Some block the view completely while others just blur it enough that people can't see details inside. I went with a semi-opaque one that still lets plenty of light through but keeps my space private. The application process was easier than I expected, just needed to clean the glass really well first. It's held up fine over the past year without peeling or fading
