Prettier forcibly migrates code to WebStorm - how to eliminate this behavior?

Question

webstorm

I installed Prettier in the project, installed FileWatcher according to the instructions in the dock, and now, when I try to write in one line:

Vue.prototype.$http.defaults.headers.common['Authorization'] = localStorage.getItem('user-token')

WebStorm automatically transfers it in this form:

I rummaged through the settings for a long time, in the options in the dock on the site, but did not find anything like it.
What is this behavior and how can I turn it off?
