Hello, I am looking to switch from manychat to botpress. Currently in manychat, I have link that customers can click or scan and it opens messenger and initiates a specifc chat flow. I wish to do the same in botpress but I don't see a way to initiate a chat from a messenger webhook. When a customer clicks a link with a referral field, it sends a webhook to back to the chatbot platform. See webhook section in https://developers.facebook.com/docs/messenger-platform/discovery/m-me-links/. In manychat I can easily set this by bringing a link node, is this possible in botpress or should I stick with manychat for now. Thanks
