function Get-TssRecordedSessionRecording {
    <#
    .SYNOPSIS
    Save the video of a recorded session
 
    .DESCRIPTION
    Downloads the video of one or more recorded sessions to a folder and returns the saved files.
    The file name is the one Secret Server returns for the video; when none is returned the file is named recorded-session-<Id> with the extension of the video type.
    A session with no processed video saves no file and writes a warning; Invoke-TssRecordedSessionRequestProcessing asks Secret Server to process it.
 
    .PARAMETER TssSession
    TssSession object created by New-TssSession for authentication
 
    .PARAMETER Id
    Recorded session ID: the launcher session GUID (LauncherSessionGuid in Search-TssRecordedSession output)
 
    .PARAMETER Output
    Folder to save the files in
 
    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    Get-TssRecordedSessionRecording -TssSession $session -Id 0d1e5c8a-6f3b-4c2e-9a7d-3b2f1e4c5d6a -Output .\recordings
 
    Saves the video of recorded session 0d1e5c8a-6f3b-4c2e-9a7d-3b2f1e4c5d6a to the recordings folder
 
    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    Search-TssRecordedSession -TssSession $session -SecretIds 42 -DateRange 7 | Get-TssRecordedSessionRecording -TssSession $session -Output .\recordings
 
    Saves the videos of the sessions of secret 42 from the last 7 days
