A word of caution here is that there is no specific installation link for this Microsoft Teams add-in. It is installed by default within the Outlook app as per the information provided above. Therefore, if you see a website that claims to have a working URL to download the Microsoft Teams URL (Other than Microsoft in the Future), we suggest that you stay away from the same.
If you want to download the Microsoft Teams app on your Desktop, you can use the link here, to head to the download page.
