I partially solved by doing the changes below. However, no map is shown on Facebook.

Another question, which are the icons after "Amsterdam"?

[christophrumpel]

Hey, the icon was the flag of Netherlands 🇳🇱

And regarding the map. This is working differently for Facebook. This is why there is a different method than to create the question object. See here: https://github.com/christophrumpel/bcwp-laraconeu-chatbot/blob/production/app/Http/Conversations/FaqLocationConversation.php

[andreshg112]

Yeah, sorry! I haven't realized that's the next part of the lesson in your book. I'll be checking it.

[christophrumpel]

Yeah np 👍

[andreshg112]

How can I use the Netherlands flag? If I try to copy it, It just copy the text "netherlands".

[christophrumpel]

Which editor do you use? Normally you should be able to just copy it. For me it works.

[andreshg112]

I'm using VS Code for Ubuntu. However, If I try to copy the flag here on Github, I get the same text "netherlands".

[christophrumpel]

Hmm I can't tell what it is not working, but maybe you can try to copy one from here https://emojikopieren.de/
