Hi @Prashardan ,

You may have a look

As mentioned in above blog below point returns required data which can be processed in frontend to extract the required group

http://localhost:4502/bin/security/authorizables.json?filter=admin

here admin is user id

Or we can write custom logic in servlet and call that servlet in frontend JS

Below is a sample servlet which returns list of principal name of groups

package com.example.group.core.servlets;//write your package name

import com.google.gson.JsonArray;
import com.google.gson.JsonObject;
import org.apache.jackrabbit.api.security.user.Group;
import org.apache.jackrabbit.api.security.user.User;
import org.apache.jackrabbit.api.security.user.UserManager;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.osgi.service.component.annotations.Component;

import javax.jcr.RepositoryException;
import javax.servlet.Servlet;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Iterator;
import java.util.logging.Logger;

@Component(
        service = {Servlet.class},
        property = {
                "sling.servlet.paths=/bin/getUserGroups",
                "sling.servlet.methods=GET"
        }
)
public class UserGroupsServlet extends SlingAllMethodsServlet {
    private static final Logger logger = Logger.getLogger(UserGroupsServlet.class.getName());
    @Override
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {
        JsonObject jsonResponse = new JsonObject();
        JsonArray groupsArray = new JsonArray();
        try {
            UserManager userManager = request.getResourceResolver().adaptTo(UserManager.class);
            User user = getUser(request.getUserPrincipal().getName(), userManager);
            if (user == null) {
                response.setStatus(HttpServletResponse.SC_NOT_FOUND);
                jsonResponse.addProperty("error", "User not found.");
                response.getWriter().write(jsonResponse.toString());
                return;
            }

            Iterator<Group> userGroups = user.memberOf();
            while (userGroups.hasNext()) {
                Group group = userGroups.next();
                if (group != null) {
                    groupsArray.add(group.getPrincipal().getName());
                }
            }

            jsonResponse.add("groups", groupsArray);
            jsonResponse.addProperty("userId", request.getUserPrincipal().getName());

        } catch (RepositoryException e) {
            response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
            jsonResponse.addProperty("error", "Repository exception: " + e.getMessage());
        }

        response.setContentType("application/json");
        response.getWriter().write(jsonResponse.toString());
    }

    private User getUser(String userId, UserManager userManager) {
        try {
            return (User) userManager.getAuthorizable(userId);
        } catch (RepositoryException e) {
            logger.severe("Error getting user: " + e.getMessage());
        }
        return null;
    }
}

Hi @Prashardan 

You need to write a custom servlet and call from javascript to know the user group.

There is a OOTB servlet but that did not return groups, just return user info
