"Activate" function with new-mgteam

We create teams for our school using Powershell. We used to use the Powershell command new-team for this. Now we use the Graph module with new-mgteam.

Since we created the teams with new-mgteam, the teams no longer need to be activated by an owner, but are activated immediately. See screenshot.

Old Command:

New-Team -DisplayName $Team -Description $Beschreibung -template EDU_Class -mailnickname $Mail -Owner $Admin

New Command:

$params = @{
                "******@odata.bind" = "https://graph.microsoft.com/v1.0/teamsTemplates('educationClass')"
                displayName = $Team
                description = $Beschreibung
                mailnickname = $Mail
                members = @(
                @{ 
                    "@odata.type" = "#microsoft.graph.aadUserConversationMember"
			         roles = @(
				     "owner"
			         )
			         "******@odata.bind" = "https://graph.microsoft.com/v1.0/users('$adminID')"
		             }      
	            )
                }
            New-MgTeam -BodyParameter $params

How can we reactivate this function? Because we want our teams to be prepared before Members can use it.
