Microsoft Teams is now available and currently supports hooks for Aha for data feeds.
Microsoft Teams also supports the ability to populate a Tab. Currently they have support for the VSO Kanban board, Power BI, Excel, etc. It would be great if you could include the ability to present elements from Aha such as the notebooks or even the roadmap slides.
It's currently possible to embed Notebooks into other web pages through an iFrame.
You can see more information about it in this support document: https://support.aha.io/hc/en-us/articles/202001117-Embed-your-published-web-Notebooks-into-another-web-page
This capability should then enable you to populate Microsoft Teams tabs with your Aha! notebook.
