function Set-TssSecretShare {
    <#
    .SYNOPSIS
    Turn permission inheritance on or off for a secret
 
    .DESCRIPTION
    Sets whether the secret inherits permissions from its folder.
    Turn inheritance off before adding explicit permissions with New-TssSecretPermission. Secret Server rejects turning it on for a secret in the root folder.
 
    .PARAMETER TssSession
    TssSession object created by New-TssSession for authentication
 
    .PARAMETER Id
    Secret ID
 
    .PARAMETER InheritPermissions
    Inherit permissions from the folder. Use -InheritPermissions:$false to break inheritance
 
    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    Set-TssSecretShare -TssSession $session -Id 42 -InheritPermissions:$false
 
    Breaks permission inheritance on secret 42
 
    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    Set-TssSecretShare -TssSession $session -Id 42 -InheritPermissions
 
    Makes secret 42 inherit permissions from its folder again
