    Connect-PnPOnline -Url $AdminSiteURL -Interactive
  
    #Get All Site collections - Exclude: Seach Center, Mysite Host, App Catalog, Redirect, Content Type Hub, eDiscovery and Bot Sites
    $SiteCollections = Get-PnPTenantSite | Where -Property Template -NotIn ("SRCHCEN#0", "REDIRECTSITE#0", "SPSMSITEHOST#0", "APPCATALOG#0", "POINTPUBLISHINGHUB#0", "EDISC#0", "STS#-1")
 
    #Loop through each site collection
    $SiteAdminData = @()
    ForEach($Site in $SiteCollections) 
    { 
        Write-host -F Yellow "Getting Site Collection Administrators of the site: " $Site.Url 
        Connect-PnPOnline -Url $Site.Url -Interactive
    
        #Get Site Collection Administrators
        $SiteAdminstrators = @()
        Get-PnPSiteCollectionAdmin -PipelineVariable Admin | ForEach-Object {
            If($_.PrincipalType -eq "SecurityGroup") #Check if its a Microsoft 365 group
            {
                #Get Members of the Group
                $Group = Get-PnPMicrosoft365Group -IncludeOwners | Where {$_.Mail -eq $Admin.Email}
                $Group.Owners | Select Email | ForEach-Object {
                    $SiteAdminstrators += $_.Email
                }
            }
            Else
            {
                $SiteAdminstrators += $Admin.Email
            }
        }
        $Adminstrators = ($SiteAdminstrators | select -Unique) -join ";"

        #Collection Site Admin Details
        $SiteAdminData += New-Object PSObject -Property @{
            'Site Name' = $Site.Title
            'URL' = $Site.Url
            'Site Collection Admins' = $Adminstrators
        }
    }

    $SiteAdminData

    #Export the data to CSV
    $SiteAdminData | Export-Csv $ReportOutput -NoTypeInformation
    Write-Host -f Green "Site Collection Admninistrators Data Exported to CSV!"
}
catch {
    write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
