Icon font doesn't show.

Question

In mobile, I don't see my label with my icons, that is a material icon font.

In windows I can see everything

1. What I am trying to achieve, is to use Icon Font in my app
2. The expected behavior is to be able to see my icons on mobile.

this is Windows

This is Android

What I did to use Icon font

• I downloaded the Google Material icons from here (https://github.com/google/material-design-icons)
• Put the desired font in Resources/Fonts
• Register the font in MaiuProgram

     builder
         .UseMauiApp<App>()
         .UseSkiaSharp()
         .UseMauiCommunityToolkit()
         .ConfigureSyncfusionCore()
         .ConfigureFonts(fonts => {
             fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
             fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
             fonts.AddFont("MaterialIconsRound-Regular.otf", "Mat");
         })
         .ConfigureEssentials(essentials => {
             essentials.UseMapServiceToken(Constants.MAPKEY);
         });

     var firebaseAuthClient = new FirebaseAuthClient(firebaseAuthConfig);

• create a static public class, using https://andreinitescu.github.io/IconFont2Code/ (So I can have intelicense)
• consume it like this LoginPage

 xmlns:inputLayout="clr-namespace:Syncfusion.Maui.Core;assembly=Syncfusion.Maui.Core"
 xmlns:sfPopup="clr-namespace:Syncfusion.Maui.Popup;assembly=Syncfusion.Maui.Popup"
 xmlns:vm="clr-namespace:DemyAI.ViewModels"
 x:DataType="vm:LoginPageViewModel">
