Like Jheasley mentioned, theres way to display sigle object/mashup/even the hub on teams as a tab in teams (like a website).
You can display these without single sign on, each users will just be prompted to log in (when viewing that tab) depending on your virtual proxy and authentication set up.
You may find my latest blog post to your interest if you are looking for ways to send notifications.
https://kabonline.net/2019/05/03/qlik-load-script-alerts-to-microsoft-teams/It covers how to send alerts to teams channel using webhook from Qlik Sense. But this can be extended further using visual extensions.
Hope this helps.
