            $Ctx.Load($RoleAssignment.RoleDefinitionBindings)
            $Ctx.ExecuteQuery()
            $PermissionLevels = ($RoleAssignment.RoleDefinitionBindings | Select -ExpandProperty Name) -join ","

            #Add the Data to Object
            $Permissions = New-Object PSObject
            $Permissions | Add-Member NoteProperty Name($Name)
            $Permissions | Add-Member NoteProperty Type($PermissionType)
            $Permissions | Add-Member NoteProperty PermissionLevels($PermissionLevels)
            $PermissionCollection += $Permissions
        }
        Return $PermissionCollection
    }
    Catch {
    write-host -f Red "Error Getting List Permissions!" $_.Exception.Message
    }
}
  
#Set Config Parameters
$SiteURL="https://crescent.sharepoint.com/sites/Marketing"
$ListName="Documents"
$ReportFile = "C:\Temp\ListPermissions.csv"
  
#Get Credentials to connect
$Cred= Get-Credential
  
#Call the function to Get List Permissions
$ListPermissions = Get-SPOListPermission $SiteURL $ListName

#Get List Permissions
$ListPermissions

#Export List Permissions to CSV File
$ListPermissions | Export-CSV $ReportFile -NoTypeInformation

and the exported CSV file looks like this:
