Hi Mjay,
Thanks for your question. We are constantly growing our portfolio of connectors so requests like this really help our prioritization. Whilst we can't commit to any specific timelines, we often hear requests for Microsoft Teams support and we'll no doubt get to it at some point down the track. Keep an eye on the website, Twitter, or mailing lists for news about connectors as they're added.
Meanwhile, you could use Custom API Sources to ingest your data into Workplace Search.
