Building, integrating, or customizing apps and workflows within Microsoft Teams using developer tools and APIs

This function is not available now in Teams. While it hasn’t been implemented yet, you can utilize outlook to still make this happen. To create a Outlook.com group and add organization members, and then make the group the recipient, it will send emails to all members of the group. For more details about its steps, you may refer to the article.
Meanwhile, to get this feature more quickly, we recommend you give the feedback in Teams UserVoice. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future. Thanks for your understanding and support.
