MicrosoftTeamsPowerShell module: Difference between Get-TeamUser and Get-TeamChannelUser

I don't understand the difference between the two cmdlets

Get-TeamUser

and

Get-TeamChannelUser

(and respectively also the add-... version).

I am currently trying to manage a Team with 1500+ participients (mostly added from a flow w/o scripting) and have ended up with...

(Get-TeamUser -GroupId deadbeef-dead-beaf-1234-1234567890ab).count
1570

(Get-TeamChannelUser -GroupId deadbeef-dead-beaf-1234-1234567890ab -DisplayName General).count
1498

So, just to enlighten me: Add-TeamUser will have to be followed by Add-TeamChanneluser for each channel in the team?

Get-TeamUser is used to retrieve the users who are members of a specific Microsoft Teams team. It gives you a list of all users who are directly added as members to the team.

Get-TeamChannelUser is used to retrieve the users who have been specifically added as members to a particular channel within a Microsoft Teams team. It allows you to view the users who have been added to a specific channel within the team.

If you want to add a user to the team, you can use the Add-TeamUser cmdlet. This will add the user as a member of the team. If you want to add the user specifically to a channel within the team, you would need to use the Add-TeamChannelUser cmdlet after adding them as a member of the team. This allows you to grant them access to the specific channel.
