When using v5.0.0 of the M365 CLI, the command:

m365 tenant status list

yields:

Error: Please use MSGraph to access this resource https://docs.microsoft.com/en-us/graph/api/resources/service-communications-api-overview?view=graph-rest-1.0&preserve-view=true

I believe the CLI is using the old API that is now deprecated and should be using the Graph API for this status information.
