I need to Add Active Directory Groups to Local Administrator Group with If state

I need to Add Active Directory Groups to Local Administrator Group on Server but I need a IF statement
Like If the Computer is in that Group then add this AD Group name to Local Administrator Group of the local computer
I need help I am still trying to create one if someone help me I’ll really appreciate that.

$g=Get-ADGroupMember -Identity “CN=myADgroup,OU=myOU,DC=corp,DC=com” -server corp.com foreach($mbr in $g) {if($name.MemberOf -like “mycomp” -eq $true)} |

You can’t do that all in one statement. You’re going to have to query its group memberships, test for the one you want, and then take whatever action - three steps. Logic statements aren’t supported in filter criteria.
