Setting custom Displayname (shortening name) for SupportedUICulture

Hi guys,

From the below code, the view displays full name of cultures by default.

@inject IViewLocalizer Localizer
@inject IOptions<RequestLocalizationOptions> LocOptions

@{
    var requestCulture = Context.Features.Get<IRequestCultureFeature>();
    var cultureItems = LocOptions.Value.SupportedUICultures
        .Select(c => new SelectListItem { Value = c.Name, Text = c.DisplayName })
        .ToList();
    var returnUrl = string.IsNullOrEmpty(Context.Request.Path) ? "~/" : $"~{Context.Request.Path.Value}";
}<div title="@Localizer["Request culture provider:"] @requestCulture?.Provider?.GetType().Name"><form asp-controller="Home" asp-action="SetLanguage"
          asp-route-returnUrl="@returnUrl"
          method="post" class="form-horizontal">
        @Localizer[""] <select id="forlang" style="max-width: 42px" name="culture" onchange="this.form.submit();"
                                        asp-for="@requestCulture.RequestCulture.UICulture.Name"
                                        asp-items="cultureItems"></select></form></div>

How can I make it so that items of select dropdown would display the cultures like I want to see. In other words, I don't want to have such a long culture names (for ex. "English (United Kingdom)") in my view, but shot names like in most of websites (for ex. "en").

Thanks in advance!
