I have followed the instructions on the link to get the desktop for Teams (https://docs.microsoft.com/en-us/microsoftteams/get-clients) to install the MS Teams Application on Ubuntu-based Linux. When I log in, the application displays a message "We are still developing Teams for Linux" and offers to put me on a list. It also provides a link back to the one above. According to that link, it should be available for use. Am I missing a step to get the Teams Application working? I have been using the web client, but it is limited and my office is using Teams for many of their meetings.
Thank you for your time and assistance to resolve this issue.
