It's not though. There are seams everywhere - between Sharepoint, Teams, OneDrive and so forth. It's the worst possible approach. Fortunately the company I work at switched to Slack the day I started (co-incidentally), so I've been able to compare and contrast the two live. Slack wins for every single use case _except_ video and audio (where Zoom or Webex are the only games in town), hands down.

That's on top of the fact that the Teams client is an absolute pig, and is incapable of remembering basic things like "which of the two cameras do I want to use" and "which audio output is appropriate".
