I'm trying to deprecate some terms based on the guid using PnP PowerShell. The command executes without error but I don't see the term deprecated in the term store. I'm using Set-PnPTerm.
$t_group = "People"
$t_set = "Department"
$t_Id = "5c92696e-f646-4a3a-95a7-826ed4947563"

Set-PnPTerm -Identity $t_Id -TermSet $t_set -TermGroup $t_group -Deprecated $true
