In which package are androidx.test.core.app.DeviceCapture.takeScreenshot or androidx.test.espresso.screenshot.captureToBitmap located

Question

I'm trying to update my screenshot routine used in the instrumentation tests of multiple projects using the new suggested method. Which is, of course, more complicated then the pervious version.

There are two options open and I'm currently trying out both.

     val screenshot1 = androidx.test.core.app.DeviceCapture.takeScreenshot()
     val screenshot2 = androidx.test.espresso.screenshot.captureToBitmap ()

However but both give me an not found error.

According to Documentation androidx.test.core.app.DeviceCapture should be part of androidx.test:core and androidx.test.espresso.screenshot part of androidx.test.espresso:espresso-core.

I include both packages yet, as mentioned, both statements still give me a not found error:

   implementation (
      [group: 'androidx.test', name: 'core', version: Androidx_Test_Version],
      [group: 'androidx.test', name: 'core-ktx', version: Androidx_Test_Version],

      [group: 'org.jetbrains.kotlin', name: "kotlin-stdlib", version: Kotlin_Plugin_Version]
   ) // implementation

The variables are all set to the newest version and the project-structure suggestions are empty.

So, what am I missing here?
