How to hide Id column from the sqlite db (DataGrid)

I was searching how to hide the Id column whenever i put the db as the item source. I saw a guide on youtube but he was using listview and I couldn't replicate it on my DataGrid. I tried using

CitizenDataGrid.Columns[0].Visibility = Visibility.Collapsed;

CitizenDataGrid.Columns[0].Visibility = Visibility.Collapsed;

but it keeps on giving an error. This is the code for showing my db in the DataGrid

public SearchDatabase()
{
    InitializeComponent();

    CitizenDataContext context = new CitizenDataContext();

    testingCitizen = new ObservableCollection<Citizen>(context.Citizens.ToList());
    
    CitizenDataGrid.ItemsSource = testingCitizen;
    //CitizenDataGrid.Columns[0].Visibility = Visibility.Collapsed;
    

}

public SearchDatabase()
{
    InitializeComponent();

    CitizenDataContext context = new CitizenDataContext();

    testingCitizen = new ObservableCollection<Citizen>(context.Citizens.ToList());
    
    CitizenDataGrid.ItemsSource = testingCitizen;
    //CitizenDataGrid.Columns[0].Visibility = Visibility.Collapsed;
    

}

This is the output of the code
