Issue in implementing Dynamic participant chooser process Step

Question

I am facing issue in implementing Participant chooser process Step.
I want to create dynamic Participant chooser process Step, I have implemented 'ParticipantStepChooser' class and overwrote 'getParticipant' method. But this process did not appear in Dynamic participant chooser dropdown in CQ5.6 environment.
I deployed same code in CQ5.5 and process appeared in Dynamic participant chooser dropdown.
This is the sample code which I have used:
@Component(immediate = true, metatype = true, label = "DMP Config Service123")
@Service
@Properties({
        @Property(name = Constants.SERVICE_DESCRIPTION, value = "A sample implementation of a dynamic participant chooser.", propertyPrivate=true),
        @Property(name = Constants.SERVICE_VENDOR, value = "Adobe", propertyPrivate=true),
        @Property(name = ParticipantStepChooser.SERVICE_PROPERTY_LABEL, value = "******** Hello ********", propertyPrivate=true),
        @Property(name = "immediate" , value = "true", propertyPrivate=true)
public class MyDynamicParticipant implements ParticipantStepChooser {
    private static final String TYPE_JCR_PATH = "JCR_PATH";
    @Activate
void activate(ComponentContext context) {
  LoggerUtil.infoLog(this.getClass(), " ");
    public String getParticipant(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap args) throws WorkflowException {
  LoggerUtil.infoLog(this.getClass(), "inside getParticipant method{} ");
        WorkflowData workflowData = workItem.getWorkflowData();
        if (workflowData.getPayloadType().equals(TYPE_JCR_PATH)) {
String path = workflowData.getPayload().toString();
String pathFromArgument = args.get("PROCESS_ARGS", String.class);
if (pathFromArgument != null && path.startsWith(pathFromArgument)) {
return "admin";
        return "administrators";

Make sure to change your imports in 5.6 to use granite api. Please change from [1] to [2].
[1]
import com.day.cq.workflow.WorkflowException;
import com.day.cq.workflow.WorkflowSession;
import com.day.cq.workflow.exec.ParticipantStepChooser;
import com.day.cq.workflow.exec.WorkItem;
import com.day.cq.workflow.exec.WorkflowData;
import com.day.cq.workflow.metadata.MetaDataMap;
[2]
import com.adobe.granite.workflow.WorkflowException;
import com.adobe.granite.workflow.WorkflowSession;
import com.adobe.granite.workflow.exec.ParticipantStepChooser;
