How to set focus to TypeAhead

[MilesGibson]

How do I set focus to TypeAhead? It does not like this:

` BlazoredTypeahead<string,string> myTypeAhead { get; set; } // it wanted a TItem,TValue so put string in here.
protected override void OnAfterRender(bool firstRender)
{
if (firstRender)
{
myTypeAhead?.FocusAsync(); // barfs on this line.
}
base.OnAfterRender(firstRender);

}`
