Issues with Blazor Treeview

I'm using Telerik Blazor TreeView Component in my Blazor C# code to display hierarchical data. Facing 2 issues with it, viz:(i) All child nodes are highlighted with a blue color although I'm not applying any style explicitly(ii) Nodes which doesn't have any children have an expand icon beside them which is not what I want.

How can I go about these 2 fixes, any suggestions?

Below is my code snippet:

Component.razor:<TelerikTreeView Data="@HierarchicalData"                 SelectionMode="@TreeViewSelectionMode.None"                 @bind-ExpandedItems="@ExpandedItems"                 @bind-SelectedItems="@SelectedItems"><TreeViewBindings><TreeViewBinding TextField="PageName" ItemsField="ChildPages"><ItemTemplate>                @{                    var item = (Page)context;                    if (item.IsNavigable)                    {<a @onclick="@(async () => await NavigateToPage(item))">@item.PageName</a>                    }                    else                    {<a>@item.PageName</a>                    }                }</ItemTemplate></TreeViewBinding></TreeViewBindings></TelerikTreeView>Component.razor.cs:private IEnumerable<object> ExpandedItems { get; set; } = new List<NavigablePage>();private IEnumerable<object> SelectedItems { get; set; } = new List<NavigablePage>(); protected override async Task OnInitializedAsync() {     // lines of code     var jsonResult = await _dataService.GetHierarchicalData(formRequest);     HierarchicalData = jsonResult.ToObject<List<Page>>();     await base.OnInitializedAsync(); }public record Page{    public Guid PageUniqueId { get; set; }    public string PageName { get; set; }    public bool IsListPage => ChildPages.Any();    public bool IsNavigable { get; set; }    public int SortOrder { get; set; }    public List<Page> ChildPages { get; set; }}
