Is it possible to create a member group programmatically

Questions

Hi.

I’m creating a memberservice, where I want to do the following:

  1. Create a member
  2. Create a page node for this member
  3. Create a member group
  4. Protect the page node with the group

I have created a controller and made this public ActionResult

[HttpPost]
    public ActionResult HandleFormSubmit(FederationCreateAthleteFormViewModel model)
    {
        //
        if (!ModelState.IsValid)
            return CurrentUmbracoPage();

        //Create member
        var memberService = Services.MemberService;

        if (memberService.GetByEmail(model.Email) != null)
        {
            ModelState.AddModelError("", "Atlet findes allerede med denne mail");
            return CurrentUmbracoPage();
        }

        //FIND MEDIAFOLDER CONTAINER
        var strMediaContainer = CurrentPage.GetPropertyValue("athleteMediaContainer").ToString();
        int intMediaContainer = Int32.Parse(strMediaContainer);
        IMedia MediaFolder = Services.MediaService.CreateMedia(model.Name, intMediaContainer, "Folder");
        Services.MediaService.Save(MediaFolder);

        var member = memberService.CreateMemberWithIdentity(model.Email, model.Email, model.Name, "dBwFAthlete");

        member.SetValue("athleteMediaNode", MediaFolder.GetUdi().ToString());
        memberService.SavePassword(member, model.Password);
        Members.Login(model.Email, model.Password);

        memberService.Save(member);

        //FIND ATHLETE CONTAINER PAGE
        var strAthleteContainer = CurrentPage.GetPropertyValue("athletePageContainer").ToString();
        int intAthleteContainer = Int32.Parse(strAthleteContainer);
        
        var newAthletePage = Services.ContentService.CreateContent(model.Name, intAthleteContainer, "federationAthletePage");
        newAthletePage.SetValue("athleteMediaFolder", MediaFolder.GetUdi().ToString());
        Services.ContentService.SaveAndPublishWithStatus(newAthletePage);

        member.SetValue("dBwFAthletePage", newAthletePage.GetUdi().ToString());

        //Create Member group with athlete name.
        //var mg = Services.MemberGroupService;
        
        //Protect Athletepage with created group
        
        //add coaches to membergroup
        
        memberService.Save(member);

        return RedirectToCurrentUmbracoPage();
        //return Redirect("/");

    }

But I am stuck where I need to create the member group. Can anybody help me?
