How to a list room's accounts that has 'LimitedDetails' accesrights in Default user?

Question

I have several room's accounts that has correct configuration set as 'LimitedDetails' in AccessRight attibute for 'Default' user, but in other hand there is a several accounts that the configuration is not correct (is set as 'AvailabilityOnly').

I need a list of accounts that has 'AvailabilityOnly' set in Default user and I did this, it works but the result shows different as I expected: "Microsoft.Exchange.Management.StoreTasks.MailboxFolderPermission" instead of "LimitedDetails" or "AvailabilityOnly".

This is my script:

$rooms=Get-Mailbox -ResultSize unlimited | where-object {$_.Recipienttypedetails -like "RoomMailbox"}  
$report_file="\\my_machine\rooms_$(Get-Date -Format yyyy_MM_dd-hh_mm_ss).csv"  
  
Add-Content $report_file "SAN;Name;DisplayName;Mail;Permission" -Encoding UTF8  
  
foreach($room in $rooms){  
    $calendar=Get-CalendarProcessing -Identity $room.Identity | select sAMAccountName,displayName,PrimarySmtpAddress  
    $id_AD=Get-ADUser  -Filter "mail -eq '$($room.UserPrincipalName)'" -Properties *  
    $room2=$room.Identity  
    $room2=$room2+"@myemail.com:\Calendar"  
    $Mailbox=Get-MailboxFolderPermission -Identity $room2 -User Default  
          
    Add-Content $report_file "$($id_AD.SamAccountName);$($room.name);$($room.displayName);$($room.PrimarySmtpAddress);$($Mailbox)" -Encoding UTF8      
}  

In fact, I need list of this from list of rooms in txt or csv file:
