Telegram Bot Welcome message

Dear members

I have created a Simple bot in telegram and added to my private group.

and connected to google drive - google script using webhook.

I can read all messages in my group when members post some things to my group except service messages like when new members join my group or throught invile link.

How can I read that type of service messages

Please help me
