Is it any way we can set the Target Audience setting

Here is the code :

private static void SetWebpartTargetAudience(ClientContext sp2013Context)
{
var pageUrl = "/sites/demokm/Pages/Test.aspx";

try
{
//get page from page url
Microsoft.SharePoint.Client.File page = sp2013Context.Web.GetFileByServerRelativeUrl(pageUrl);
sp2013Context.Load(page, p => p.Properties, p => p.CheckOutType);
sp2013Context.ExecuteQuery();

//Check Out page, if page is checked-In
if (page.CheckOutType == CheckOutType.None)
{
page.CheckOut();
}

LimitedWebPartManager wpm = page.GetLimitedWebPartManager(PersonalizationScope.Shared);

sp2013Context.Load(wpm.WebParts, wps => wps.Include(wp1 => wp1.WebPart.Title, wp1 => wp1.Id));
sp2013Context.ExecuteQuery();

WebPartDefinition wpd = wpm.WebParts[0];

sp2013Context.Load(wpd, w => w.WebPart.Properties);
sp2013Context.ExecuteQuery();
//single target audience i.e sharepoint group
wpd.WebPart.Properties["AuthorizationFilter"] = ";;;;" + "SharePoint Group Name";
//multiple target audience i.e sharepoint groups
//wpd.WebPart.Properties["AuthorizationFilter"] = ";;;;" + "SharePoint Group Name1,SharePoint Group Name";
wpd.SaveWebPartChanges();
sp2013Context.Load(wpd);
page.CheckIn("checkin comments", CheckinType.MajorCheckIn);
sp2013Context.ExecuteQuery();
}
catch (Exception)
{
throw;
}
}

//Call this method
SetWebpartTargetAudience(SharePointContext);
