RedBOT reply message route telegram - Track problem

So I switched from the Telegram messenger (which has a simple switch for a pop up yes or no answer in chat) to using RedBot for more features.

In a flow (from telegram in). Words are filtered. Then a question is asked which is great. But I'd like to integrate a confirmation response of Yes or No (Like the switch in telegram).

So on the telegram sender node there is an option:

It lies. Because I put a debug node on the output of the sender node. And the message is sent and I reply. Nothing comes back to the output pin.

I'm sure its me being a bit of a noob. But the the Telegram integration was much simpler.

Any help guys?

Sorted. WIll edit this and pop the resolve on later :ok_hand:
