Change boolean value in listview WPF

Hello all,
I have been working on figuring out this problem for quite some time now. I am pulling a user object from a database and displaying it in a listview in WPF C#. I can read the data and I have the data separated in columns. I have a Boolean value(bit) in SQL and in my column it displays True/False. In my listview I want it to display Yes/No instead of True/False.
I tried making a method but I am not sure how to call the method in the listview. I tried making a separate template for my Boolean column but still no luck. I am not sure if this is the way I should be trying to do this or not so any input / feedback would be much appreciated.
Thank you.

C#

      private void PopulateListBox(){
            lstUserList.Items.Clear();
            users = UsersDB.GetUsersList();
            foreach(User user in users){
                lstUserList.Items.Add(user);
            }
        }
        public static string MakeBooleanYesOrNo(this bool value){
            string boolvalue = "";
            if (value.ToString() == "True"){
                boolvalue = "Yes";
            }else{
                boolvalue = "No";
            }
            //return value.ToString();
            return boolvalue;        }


//This is how I display the data In my listview
<GridViewColumn Header="Admin" Width="50px" DisplayMemberBinding="{Binding IsAdmin}"/>


//I was also thinking maybe something like this if I can do this in C# not ASP.net
<ItemTemplate><%# (Boolean.Parse(Eval("Active").ToString())) ? "Yes" : "No" %></ItemTemplate>

What I have tried:

I have tried making my own method and different templates but im not sure how to call my method in a template or if this is the way i should be going with this

implement IValueConverter like this

public class BoolToVisibilityConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            var boo = value != null && (bool)value;
            return boo ? Visibility.Visible : Visibility.Collapsed;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return DependencyProperty.UnsetValue;
        }
    }

Create an instance and use it when you binding data in your xaml file.
