    .SYNOPSIS
        Retrieves a behavior of the process.
         
    .DESCRIPTION

        Optional parameter to expand specific properties of the behavior (e.g., fields, combinedFields, none).
         
    .PARAMETER ApiVersion
        The version of the Azure DevOps REST API to use. Default is "7.1".
         
    .EXAMPLE
        Get-ADOProcessBehavior -Organization "fabrikam" -Token "my-token" -ProcessId "906c7065-2a04-4f61-aac1-b5da9cef040b" -BehaviorRefName "System.RequirementBacklogBehavior"
         
        Retrieves the specified behavior for the process.
