MS Teams 2.0 status in OUTLOOK 365 not showing

Hi there

Hello there!

our company just moved from Skype from business to MS Teams, However, Outlook (64-bit) is not showing the status of Teams.

also, I have checked the registry path: HKEY_CURRENT_USER\Software\IM Providers

but all the steps I found on the Internet are not working, and the below image is an example I found it in the Internet, Does anyone have any idea what to do?

also, I noticed that on my Teams client, I don't have this option AT ALL! (Register the new Teams as the chat app for Microsoft 365(requires restarting Microsoft 365 applications))
