SharePoint Online: Set Mutli Value User Profile property with REST API

Set.Mult.UserProfileProperty.js

(function ($) {
    'use strict';

    var requestHeaders = {
        'X-RequestDigest': $("#__REQUESTDIGEST").val(),
        "accept": "application/json; odata=nometadata",
        "content-type": "application/json;odata=nometadata"
    };

    var userData = {
        'accountName': "i:0#.f|membership|user@yourtenant.onmicrosoft.com",
        'propertyName': 'SPS-Skills', //Can also set custom userprofile properties.
        'propertyValues': ["SharePoint", "Office 365", "Architecture", "Azure"]
    };

    $.ajax({
        url: _spPageContextInfo.webAbsoluteUrl + "/_api/SP.UserProfiles.PeopleManager/SetMultiValuedProfileProperty",
        type: "POST",
        headers: requestHeaders,
        data: JSON.stringify(userData),
        success: function (data) {
            console.log(data)
        },
        error: function (jqxr, errorCode, errorThrown) {
            console.log(jqxr.responseText);
        }
    });

})(jQuery);

Hi vman, Thank you for your example. I used the same approach in MS Flow and it works great so far but I'm not able to update user profile properties of guest user's in SharePoint Online. I'm gettting the error "403 - Access Denied".
Do you know if perhaps this is a known restrictions or if it should work?
