RE: How to add users in the teams chat via integration

Don't know if this will work, I combined Example #2 (group chat) and #3 (using the userprincipalName in lieu of the uuid)

learn.microsoft.com/.../chat-post

{
  "chatType": "group",
  "topic": "Group chat title",
  "members": [
    {
      "@odata.type": "#microsoft.graph.aadUserConversationMember",
      "roles": ["owner"],
      "user@odata.bind": "https://graph.microsoft.com/v1.0/users('jacob@contoso.com')"
    },
    {
      "@odata.type": "#microsoft.graph.aadUserConversationMember",
      "roles": ["owner"],
      "user@odata.bind": "https://graph.microsoft.com/v1.0/users('alex@contoso.com')"
    }
  ]
}

If you want to add members to an already existing group chat, you should use the addMembers endpoint.

learn.microsoft.com/.../chat-post-members

{
    "@odata.type": "#microsoft.graph.aadUserConversationMember",
    "user@odata.bind": "https://graph.microsoft.com/v1.0/users('jacob@contoso.com')"
    "roles": ["owner"]
}
