Kotlin K1 to K2 plugin migration. analysisCompleted, binding context slicing

Question

I need a suggestion on K1->K2 Kotlin compiler plugin migration.

I have a K1-compatible plugin that overrides AnalysisHandlerExtension::analysisCompleted and uses a bindingContext to get a slice of TYPEs used in compilation:

bindingContext.getSliceContents(BindingContext.TYPE)

Full K1 plugin code snippet:

class Ext: AnalysisHandlerExtension {
  override fun analysisCompleted(
      project: Project,
      module: ModuleDescriptor,
      bindingTrace: BindingTrace,
      files: Collection<KtFile>
  ): AnalysisResult? {   
  ...
    bindingTrace.bindingContext.getSliceContents(BindingContext.TYPE).values.forEach {
      record(it)
    }
  ...

}

Question

What is the most appropriate way to implement it using K2?

We likely need two things: first, an analysisCompleted analogue, and second, a bindingContext.getSliceContents analogue. Any suggestions?
