Hierarchy DataGrid not Expanding Rows

Greetings,
I'm facing an issue with an Hierarchy DataGrid not showing "subrecords"
I'm can't seem to realize what I'm doing wrong, since I already have the "subrecord" data "ready to display"

<RadzenDataGrid @ref="modulesGrid"
    TItem="AuthorizationProfileModel"
    AllowFiltering="true"
    AllowSorting="true"
    Data="@modulesList"
    RowRender="@RowRender"
    RowClick="OnRowClick"
    RowSelect="OnRowSelect"
    LoadChildData="LoadChildData"
    RowCollapse="@(args => modulesGrid.ColumnsCollection.ToList().ForEach(c => c.ClearFilters()))">
            <Columns>
            <RadzenDataGridColumn Frozen="true" Sortable="false" Filterable="false" Width="300px">
                <Template Context="data">
                        @data.ModuleName
                </Template>
            </RadzenDataGridColumn>
        </Column>
</RadzenDataGrid>
async void RowRender(RowRenderEventArgs<AuthorizationProfileModel> args)
{
    args.Expandable = (await AuthorizationProfilesFactory.GetLoginPermissions(dbAccess, selectedUser, $"{args.Data.Module}_1")).ToList().Any();
    //args.Expandable = modulesList.Any() ;
}

async void LoadChildData(DataGridLoadChildDataEventArgs<AuthorizationProfileModel> args)
{
    try
    {
        args.Data = await AuthorizationProfilesFactory.GetLoginPermissions(dbAccess, selectedUser, $"{args.Item.Module}_1");
        //await modulesGrid.ExpandRow(args.Item);
    }
    catch (Exception ex)
    {
        NotificationService.Notify(new NotificationMessage
            {
                Severity = NotificationSeverity.Error,
                Summary = "Erro: ",
                Detail = ex.Message,
                Duration = 5000
            });
    }
}

Best Regards,

Async voids are not recommended:

Use async Task instead:

Thank you very much for your help, I didn't realise that
