function Approve-TssDualControl {
    <#
    .SYNOPSIS
    Authorize a dual control as an approver
 
    .DESCRIPTION
    A dual control requires a member of an approval group to authorize an action (running a report, viewing a secret session recording, viewing all secret sessions) before it can proceed.
    The approver authorizes the action on the given item by entering their own credentials; the result says whether the authorization succeeded. The approver must be a member of an approval group of the dual control and another user than the one signed in to the session; otherwise the server answers API_DualControlAuthFailed.
    The request body carries the approver password and is never written to the verbose stream or the ShouldProcess message.
 
    .PARAMETER TssSession
    TssSession object created by New-TssSession for authentication
 
    .PARAMETER DualControlType
    Type of item: Report, UserAuditReport, Secret, CreateReport or AllSecretSessions
 
    .PARAMETER Id
    Item ID (report ID or secret ID); 0 for AllSecretSessions
 
    .PARAMETER Credential
    Credential of the approver (a member of one of the approval groups)
 
    .PARAMETER DomainId
    Domain ID of the approver, for a domain account; omit for a local account
 
    .PARAMETER TwoFactorToken
    Two-factor token of the approver, when the approver has two-factor authentication
 
    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    $approver = Get-Credential
    Approve-TssDualControl -TssSession $session -DualControlType Report -Id 21 -Credential $approver
 
    Authorize running report 21 as the approver in $approver
 
    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    Approve-TssDualControl -TssSession $session -DualControlType AllSecretSessions -Id 0 -Credential $approver -DomainId 1 -TwoFactorToken 123456
 
    Authorize viewing all secret sessions as a domain approver with a two-factor token
