Hello @MS
As far as I know there are no such commands by default, but you could find a lot of scripts publisher around in order to extract reports of your channels/teams. There is a lot of information in the microsoft techcommunity, have a look here:
Get all Teams and channel information using PowerShell
https://techcommunity.microsoft.com/t5/microsoft-teams/get-all-teams-and-channel-information-using-powershell/m-p/1312145
Get-Team
https://learn.microsoft.com/en-us/powershell/module/teams/get-team?view=teams-ps
Nice way to get a list of all our Teams and their info:
