Rich links sent with the golang API are displayed as [object Object] in intercom's dashboard.

Steps to reproduce

	event := intercomlib.Event{
		UserID:    userId,
		EventName: eventName,
		CreatedAt: int64(time.Now().Unix()),
		Metadata:  map[string]any{
				some_rich_link: map[string]any{
                                                  "url":   "https://www.some-custom-url.com",
				                 "value": "some-custom-name",
                                  },
			},
	}

	ic.Events.Save(&event)
