Predecessors and Successors do not work when using SaveOptions for Excel

Predecessors and Successors do not work when using SaveOptions.
I am using PostTaskDocumentWithFormat API with saveoptions in golang, trying to display Predecessors and Successors but it is not working. here is the sample used.

   type (
	Column = struct {
		Type     string
		Name     string
		Property string
		Width    int
	}
	View = struct {
		Columns []Column
	}
	saveOptions = struct {
		View View
	}
)

so := saveOptions{
	View{
		[]Column{
			{"GanttChartColumn", "ID", "Id", 120},
			{"GanttChartColumn", "Active", "IsActive", 120},
			{"GanttChartColumn", "Name", "Name", 120},
			{"GanttChartColumn", "Duration", "Duration", 120},
			{"GanttChartColumn", "Start", "Start", 120},
			{"GanttChartColumn", "Finish", "Finish", 120},
			{"GanttChartColumn", "Predecessors", "Predecessors", 120},										 
                         {"GanttChartColumn", "Successors", "Successors", 120},
		},
	},
}
opts := &requests.PostTaskDocumentWithFormatOpts{
	Name:        "data1.mpp",
	SaveOptions: so,
	Format: string(models.XLSX_ProjectFileFormat),
	Folder: optional.NewString(remoteBaseDataFolder),
}
data, response, err := tasksApi.PostTaskDocumentWithFormat(ctx, opts)
if err != nil {
	return
}

can you tell me what properties are provided for the GanttChartColumn view and how to display Predecessors and Successors?
