origin of 'totalEmployees' variable in code example not clear

[NikolaJacques]

Description

Not sure whether this is an issue or not, but in the code example below I noticed that a 'totalEmployees' variable is used, which I cannot gather from context where it comes from / where it gets its value:

private async ValueTask<ItemsProviderResult<Employee>> LoadEmployees(
    ItemsProviderRequest request)
{
    var numEmployees = Math.Min(request.Count, **totalEmployees** - request.StartIndex);
    var employees = await EmployeesService.GetEmployeesAsync(request.StartIndex, 
        numEmployees, request.CancellationToken);

    return new ItemsProviderResult<Employee>(employees, **totalEmployees**);
}

Hello @NikolaJacques ... It would be pulled from the service (probably) and assigned to that field via a method call elsewhere in the component, such as during initialization. I'll make a remark for that example. Leave this issue open, as it will close automatically when the PR merges later. Thanks for the issue!
