Why the getSortIndex() method does RadzenDataGridColumn have an internal visibility modifier?

Hello! I am writing my blazor component based on RadzenDataGrid. I need to create a new object of type DataGridColumnSettings, but I can't access the getSortIndex() method at RadzenDataGridColumn. For what reason was it made internal and not protected or public?

Since this method is using internal stuff and it’s not for public use. Feel free to suggest a change via pull request.
