ms team bot的conversation.id是独一无二的吗？

Question

In ms teams bot. for group chat and for personal chat, I received following conversation object.

conversation: {
  isGroup: true,
  conversationType: 'groupChat',
  tenantId: '3fef5931-0c12-4eb9-b22f-xxxxxxx',
  id: '19:abad7298-34e2-4437-ad7d-xxxxxxxxxxxx-224f-4e50-xxxxxxde65@unq.gbl.spaces'
},

conversation: {
  conversationType: 'personal',
  tenantId: '3fef59xxxxxxxxxxxxxxxd03d',
  id: 'a:1fIazkAU3MCwYcbsr1nZcpg_VTMw8OuWxxxxxxxxxxxxKKVpzEgbeiqrnT3B8eM856iyI6G61qoeXU0UXt7XkGpbmi0As9-mV1h2Ywz-Coi'
},

1. Is the id for both the conversation unique ? Do the id changes in case of personal or group chat after some days ?
2. Can i use it as unique identifier ?
