'clientSecret null error for UserAssignedMSI AzureBot

I'm having some troubles with authentication when setting up my Bot Framework SDK webchatbot. The bot have been setup in Azure and when testing the bot in the https://webchat.botframework.com/ I get the error with the message: [OnTurnError] unhandled error : Value cannot be null. (Parameter 'clientSecret').

I don't have a client secret which is why I'm slightly confused. my basic appsettings are:

{
  "MicrosoftAppType": "UserAssignedMSI",
  "MicrosoftAppId": "<<AZURE BOT APP ID>>",
  "MicrosoftAppPassword": "",
  "MicrosoftAppTenantId": "<<TENANT GUID ID>>"
}

I'm not entirely sure how to setup authentication as I hoped that the app service in azure would use its identity to automatically authenticate up against the azure bot service and the other services/channels. Any help or links to guides are appreciated. Also would like to know a way to authenticate my locally running code as I get a 401 in the Bot Emulator.

Failing code

protected override async Task OnMembersAddedAsync(IList<ChannelAccount> membersAdded, ITurnContext<IConversationUpdateActivity> turnContext, CancellationToken cancellationToken)
        {
            var welcomeText = "Hello and welcome!";
            foreach (var member in membersAdded)
            {
                if (member.Id != turnContext.Activity.Recipient.Id)
                {
                    await turnContext.SendActivityAsync(MessageFactory.Text(welcomeText, welcomeText), cancellationToken);
                }
            }
        }

According to the error, you require the Azure Active Directory implementation with Bot Framework and I guess that was missing in the implementation.

Check the below links for the better implementation and authentication
