Describe the bug

Proxy settings are passed into Botframework ConnectorClient like so:

  const serviceUrl = 'https://smba.trafficmanager.net/teams/';
  const credentials = new MicrosoftAppCredentials(appId, appPassword);
  const clientOptions: ConnectorClientOptions = { baseUri: serviceUrl };
  clientOptions.proxySettings = {
    host: hostname,
    port: proxy_port,
    username: proxy_username,
    password: proxy_password,
  };
  const client = new ConnectorClient(credentials, clientOptions);

The client is then used to send a proactive message to Teams like so:

client.conversations.createConversation({
      bot: {
        id: appId,
        name: botty,
      },
      isGroup: true,
      channelData: {
        channel: { id: channelId },
      },
      activity: message,
    });

This results in the following error:

ClientAuthError: endpoints_resolution_error: Error: could not resolve endpoints. Please check network and try again. Detail: ClientConfigurationError: untrusted_authority: The provided authority is not a trusted authority. Please include this authority in the knownAuthorities config parameter.

To Reproduce

Steps to reproduce the behavior:

1. Set up a proxy
2. Create an Azure bot and enable teams channels
3. set up a password in the azure bot. Grab the app id and app password
4. upload a custom app to teams and specify the app id in the manifest
5. create a node project that uses the above code to create a connector client, pass in the proxy details via proxysettings, and use the client to send a proactive message to Teams.

Expected behavior

message is sent successfully to Teams through the proxy.

@tracyboehrer The code above is consistent with option 2 in the sample. I have had success testing this on straightforward proxy, but in more complex proxy scenarios, we run into this ClientAuthError. In one such case, we have a customer using a Cisco ironport proxy where this ClientAuthError occurs on every call to client.conversations.createConversation().
