' The bootstrap secret will contain the following information:

' Azure Tenant ID
' Azure Client ID
' Azure Client Secret

' 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.
