onMembersAdded Event Not Triggering on an App Service with Authentication Enabled

[hirokika]

Hi,

I am developing a notification bot in TypeScript based on the Teams Toolkit sample code.

I use the NotificationBot#findMember method to identify users and send notifications to those who have installed the bot.
https://learn.microsoft.com/en-us/javascript/api/@microsoft/teamsfx/botbuildercloudadapter.notificationbot?view=msteams-client-js-latest

Everything was working fine until I enabled Microsoft IdP authentication on the App Service for access control. Since then, the bot has stopped sending notifications.

While investigating the issue, I tried logging a message to the console when the bot is installed, but noticed that no messages are output when authentication is enabled. Below is an example of the debugging code:

this.onMembersAdded(async (turnContext, next) => {     
   await turnContext.sendActivity("Welcome!! You can receive notifications.");     
   await next();  
});

It also appears that the bot is not writing the user’s connection information to the connected storage.

Could there be any possible causes for this? When adding the bot in Teams, do I need to explicitly allow the request? If so, could you please provide the specific configuration steps?
