Get Manager Property from Azure AD using Graph API

I have referred to the article "Use Graph API to access user profile properties," but encountered an issue where the Manager property is not retrieved. Upon further investigation, I realized that a separate request is required to obtain the manager's name using the Graph API. Can someone assist me with the syntax for this separate request?

This is my request :

Hello @madhawa.rajapaksha,

There is a separate request for getting the manager in Graph APi: List manager - Microsoft Graph v1.0 | Microsoft Learn

I would suggest using PnPjs instead to retrieve the manager property:

function updateUserInfo() {
    var employee = fd.field('User').value;

    if (employee && employee.Key){
        pnp.sp.profiles.getPropertiesFor(employee.Key).then(function(result) {

            var props = result.UserProfileProperties;

            for (var i = 0; i < props.length; i++) {

                switch (props[i].Key) {
                    case 'Manager':
                        fd.field('Manager').value = props[i].Value;

                    case 'Department':
                        fd.field('Department').value = props[i].Value;

                    case 'Title':
                        fd.field('JobTitle').value = props[i].Value;

                    case 'CellPhone':
                        fd.field('Mobile').value = props[i].Value;

fd.spRendered(function() {
    //executes updateUserInfo on field change
    fd.field('PersonFieldName').$on('change', updateUserInfo);
