Fiter not working

I’m trying to use your example filter to adjust the output of an ACF date field. But it’s having no effect:

function my_column_value($rendered_output, $field_properties, $field_value, $post_id) {
    if ($field_properties['name'] == 'date') {

		$field_value = DateTime::createFromFormat('Ymd', $field_value);
		return $field_value->format('Y-m-d');
		
    }
    return $rendered_output;
}
add_filter('acf/admin_columns/column/render_output','my_column_value', 10, 4);

The ACF field name is “date” and the value is saved in Ymd format. I want to change it to Y-m-d when displayed in the admin column. Nothing is happening.

I tested simplifying the return in case my date function was wrong, but this still had no effect:

function my_column_value($rendered_output, $field_properties, $field_value, $post_id) {
    if ($field_properties['name'] == 'date') {

         return 'test';
		
    }
    return $rendered_output;
}
add_filter('acf/admin_columns/column/render_output','my_column_value', 10, 4);

What am I doing wrong?
