Get a report showing specific shared mailboxes and Display Names of their members on one line.

I was able to get what I wanted, although the Display Names are not sorted alphabetically. Thank you VasilMichev This is the code:

$jobs = Get-ExoMailbox -RecipientTypeDetails SharedMailbox -Filter {DisplayName -like "jobs-*"} | Sort-Object DisplayName

$JobsReport = @()

foreach ($job in $jobs) {
    $members = Get-MailboxPermission -Identity $job.Identity | Where-Object { ($_.User -like '*@*')
    
$memberNames = @()

   foreach ($member in $members) {
        $memberName = (Get-Mailbox $member.User).DisplayName
        $memberNames += $memberName
   }

$membersString = $memberNames -join ", "

    $JobsReport += [PSCustomObject]@{
        "Jobs Accounts" = $job.DisplayName
        "Members with Full Access" = $membersString
    }
}

$JobsReport = $JobsReport | Sort-Object "Jobs Accounts"
