Just add addSbtPlugin("com.github.sbt" % "sbt-jacoco" % "3.4.0") to your plugins.sbt and execute sbt jacoco. After that you should see a HTML report in your path target/scala-2.13/jacoco/report/

You can configure jacoco by you needs e.g. generating a HTML and a XML by adding

jacocoReportSettings := JacocoReportSettings().withFormats(JacocoReportFormats.XML, JacocoReportFormats.HTML)

in your build.sbt.
