Populating listbox as I type

Question

Hello

I am tryng to suggest places to my user as they type to a textbox.
I already declared a Listox in order to show the results, but I do not know how to call the api as the user type, and show the listbox with places.

App https://github.com/eduardoagr/RsidentsManager

For example: like how Bingsugget places as you type

By thhe way I am using Bing Api to do this and MVVM

UI

<TextBox
materialDesign:HintAssist.Hint="Address"
materialDesign:HintAssist.IsFloating="True" />

        <ListBox Visibility='Collapsed' />  

Services - Api Method

public static async Task<List<string>> CallApi(string query) {

        using (var client = new HttpClient()) {  

            var list = new List<string>();  

            client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", subscriptionKey);  

            var content = await client.GetAsync(requestUri: $"{baseUri}?{QUERY_PARAMETER}{query}{MKT_PARAMETER}");  

            if (content.IsSuccessStatusCode) {  

                string jsonContent = await content.Content.ReadAsStringAsync();  
                SearchSuggestion response = JsonConvert.DeserializeObject<SearchSuggestion>(jsonContent);  
                  
                if (response.Query != null) {  
                    list.Add(response.Query);  
                }  
            }  

            return list;  
        }  
    }  

VM
public class PrpertiesWindowViewModel : BaseViewModel {

    public List<int> Rooms { get; set; }  

    public PrpertiesWindowViewModel() {  

        Rooms = new List<int>();  
        FillList();  

    }  

    private void FillList() {  

        for (int i = 1; i < 5000; i++) {  
            Rooms.Add(i);  
        }  
    }  
}  

}
