UWP Community Toolkit, DataGrid control: how to align cell content to the right

I have a numeric column in a DataGrid that I want your content to be aligned on the right. I read the documentation , especially Customizable templates and styling for cells, rows and headers where I ended up with this code to get the contents of the cell aligned right:

<controls:DataGrid.CellStyle>
    <Style TargetType="controls:DataGridCell">
        <Style.Setters>
            <Setter Property="HorizontalAlignment" Value="Right"/>
        </Style.Setters>
    </Style>
</controls:DataGrid.CellStyle>

As you might expect, this code really does what I want, but with all cells. I want only the numeric column to have this property, and only it, but I have been unable to achieve this.

What am I doing wrong?
