function Get-TssWorkflowTemplateStep {
    <#
    .SYNOPSIS
    Get the steps of a workflow template
 
    .DESCRIPTION
    Workflow templates define the approval steps of secret access requests and secret erase requests. Managing them requires the Administer Workflows permission and a Secret Workflow license.
    Returns every step of the workflow template, or one step with -StepNumber. Each step carries its approvers, the number of approvals required and the steps that follow an approval or an expiration.
 
    .PARAMETER TssSession
    TssSession object created by New-TssSession for authentication
 
    .PARAMETER Id
    Workflow template ID
 
    .PARAMETER StepNumber
    Order of the step in the template (1 for the first step); returns only that step
 
    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    Get-TssWorkflowTemplateStep -TssSession $session -Id 4
 
    Get every step of workflow template 4
 
    .EXAMPLE
    $session = New-TssSession -SecretServer https://alpha -Credential $ssCred
    (Get-TssWorkflowTemplateStep -TssSession $session -Id 4 -StepNumber 2).Configuration.ApproverGroups
 
    List the approvers of the second step of workflow template 4
