    // The bootstrap secret will contain the following information:

    // Azure Tenant ID
    // Azure Client ID
    // Azure Client Secret

    // or in the local manager (Windows Credentials Manager or Apple Keychain)
    // Setup Bootstrap Secret in Local Manager
    // Setup Bootstrap Secret in Memory

    // Set the location of the bootstrap secret.
    // Can be "local_manager" or "memory", depending on how you setup the bootstrap secret.
    // ---------------------------------------------------------------------------------------------
    // If your operating system is NOT Windows or MacOS/iOS, then change "local_manager" to "memory"
    // You can also, if desired, use "memory" on Windows and MacOS/iOS if your bootstrap secret was previously setup in memory.
    // ---------------------------------------------------------------------------------------------

    // Specify the bootstrap secret to be used.
