How to make gulp-svgmin not remove classes from svg?

Question

gulp.js

Hello.
I use a task to create svg sprites.

gulp.task('svg', function () {
  return gulp.src('src/assets/i/svg/inline/*.svg')
    .pipe(cheerio(cleanSvg({
      tags: ["title", "desc"],
      attributes: ["style", "fill*", "clip*", "stroke*"]
    })))
    .pipe(svgmin({
      js2svg: {
        pretty: true
      }
    }))
    .pipe(replace('>', '>'))
    // .pipe(svgSprite({
    // 	mode: {
    // 		symbol: {
    // 			sprite: "../sprite.svg",
    // 		}
    // 	}
    // }))
    .pipe(gulp.dest("build/assets/i/svg/inline/"));
});

At the entrance I have this picture

<?xml version="1.0" encoding="utf-8"?>

<rect y="40" width="48" height="3"/>
</svg>

After working out gulp-svgmin I get

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 48 48">
    <path d="M0 0h48v48H0V0z" fill="none"/>

</svg>

Not a bad result. Only before the plugin was worked out, the paths had classes, and after that they are not. How to style from css now?
I did not find an option for this plugin to not delete classes.

Solved the problem in the following way.
At the initial stage, in the src folder for the icons that need to be added to the sprite, I delete the style attribute along with the content.
