Why am I getting this error message: "'IMediaManager' does not contain a definition for 'MediaExtractor'" with xamarin.forms?

Question

I am developing an app that can also Livestream Video, but I am having some issues.

I have downloaded and installed Plugin.MediaManager.Forms (and also Plugin.MediaManager) via Nuget. I have also done the needful as you can see below:

In MainActivity.cs (I am referencing MediaManager & I also Initialized CrossMediaManager)

    using Android.App;
    using Android.Content.PM;
    using Android.Runtime;
    using Android.OS;
    using MediaManager;
    namespace Abuse_Alert.Droid
    {
       [Activity(Label = "Abuse_Alert", Icon = "@mipmap/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation | ConfigChanges.UiMode | ConfigChanges.ScreenLayout | ConfigChanges.SmallestScreenSize )]

   public class MainActivity : 
   global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
   {
    protected override void OnCreate(Bundle savedInstanceState)
    {
        CrossMediaManager.Current.Init(this);

        base.OnCreate(savedInstanceState);

        Xamarin.Essentials.Platform.Init(this, savedInstanceState);
        global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
        LoadApplication(new App());
    }
    public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Android.Content.PM.Permission[] grantResults)
    {
        Xamarin.Essentials.Platform.OnRequestPermissionsResult(requestCode, permissions, grantResults);

        base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
    }
   }
    }

The XAml File looks like this:

<?xml version="1.0" encoding="utf-8" ?>
    <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         x:Class="AbuseAlert.Views.Page1"
         xmlns:mm="clr-namespace:MediaManager.Forms;assembly=MediaManager.Forms"
         x:Name="BrowseItemsPage">

<ContentPage.Content>
<mm:VideoView VerticalOptions="FillAndExpand"
              HorizontalOptions="FillAndExpand"
              BackgroundColor="Black"
              x:Name="mmVideoView"
              />
</ContentPage.Content>

</ContentPage>

In the code behind, this is what I have done:

    if (isHLS)
    {
      var item2 = await CrossMediaManager.Current.MediaExtractor.CreateMediaItem(URL);

      item2.MediaType = MediaManager.Media.MediaType.Hls;
      CrossMediaManager.Current.MediaPlayer.VideoView.ShowControls = false;

      await CrossMediaManager.Current.Play(item2);
   }
   else
   {
      await CrossMediaManager.Current.Play(URL);
   }

Nevertheless, these are the error messages I am getting in 3 above:

1. The name 'isHLS' does not exist in the current context

2. 'IMediaManager' does not contain a definition for 'MediaExtractor' and no accessible extension method 'MediaExtractor' accepting a first argument of type 'IMediaManager' could be found (are you missing a using directive or an assembly reference?)

3. The type or namespace name 'MediaType' does not exist in the namespace 'MediaManager.Media' (are you missing an assembly reference?)

4. 'IVideoView' does not contain a definition for 'ShowControls' and no accessible extension method 'ShowControls' accepting a first argument of type 'IVideoView' could be found (are you missing a using directive or an assembly reference?)

So, what am I supposed to have done that I have not done? I am using VS 2022 with xamarin.forms.
