Custom message templates for Telegram, Messenger, etc

So I’m trying to create custom messages for Telegram and Messenger (optimally from a single template). It works perfectly for Telegram, but fails with Messenger. Currently, it looks like this:

domain.yml

  utter_link:
    - custom:
        text: "[Click here]({link})"
        parse_mode: markdown

actions.py

class ActionLink(Action):
    def name(self) -> Text:
        return "action_link"
    def run(self, dispatcher: CollectingDispatcher,
            tracker: Tracker,
            domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
        dispatcher.utter_message(template="utter_link", link='https://google.com/')
        return []

I’ve tried the following but with no luck. I changed actions.py to:

class ActionLink(Action):
    def name(self) -> Text:
        return "action_link"
    def run(self, dispatcher: CollectingDispatcher,
            tracker: Tracker,
            domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
        custom = {}  # format missing here
        dispatcher.utter_message(json_message=custom)
        return []

Any advice on how I could change it to work for both (possible more channels) from a single template?

Try this:

dispatcher.utter_custom_json(custom)
