​@MartinD Yes, that is possible! You can just use the normal Facebook comment trigger for this.
Also, instead of sending a link, I recommend creating a Chat Funnel in Messenger. Chat Funnels have a 50% conversion rate, while landing pages only have a conversion rate of 5%.
That means you can 10X your leads just by changing from a landing page to a Chat Funnel.

Hi ​@Joren Wouters - thanks for a quick respons!

That sounds great! - Is it also possible for Facebook Livestreams in groups / events? 
Right now, in the trigger, I can only see my public posts on my main Facebook page, and not the posts I have made in a group / in a event. 
Will that be the same for livestreams? 

Best regards

​@MartinD Facebook bots don’t work in Facebook groups, unfortunately. Meta doesn’t allow that, it only works with posts on your Facebook page.
