    clientId: "<CLIENT_ID>",
    clientSecret: "<CLIENT_SECRET>"
});

// Get All Connections
const getAllConnection = await client.connections.getAll();
console.log("getAllConnection", getAllConnection);

const createConnectionPayload: ConnectionCreate = {
    name: "new-connection",
    strategy: "auth0",
    authentication: {
      active: false
    }
}

// Create Connection
const createConnection = await client.connections.create(createConnectionPayload);
console.log("createConnection", createConnection);

const updateConnectionPayload: ConnectionUpdate = {
  connected_accounts: {
    active: false,
    cross_app_access: false
  }
}

// Update Connection
const updateConnection = await client.connections.update({ id: createConnection.data.id! }, updateConnectionPayload);
console.log("updateConnection", updateConnection);
