Controlling settings, permissions, and membership within Teams and channels
Hi brainiac122,
I'm afraid that there is no such a option/connector your can easily use to accomplish your requirement in Teams. You need to take some time and deploy a bot by yourself. It also requires programming skills and admin level permission. It's suggest that contact your IT admin and see if they can help you with this request.
For the instructions for bots deployment, the admin can refer to the following article: https://docs.microsoft.com/en-us/microsoftteams/platform/bots/how-to/conversations/send-proactive-messages?tabs=dotnet
Best Regards,
SD
