Apart from payload, image what else could we have under buttons ? Did it support file(txt, pdf, docx,etc) or links ? How to decide what should happen after user clicks button?
do you mean that you want to add attachments?
Current I have passed hyperlink which get open on new tab but after I click on particular button it leads to display fallback msg
if you want to send the link u can send it as a text.
I did that only. added link to txt field
But the problem is that after clicking on buttons it either respond back a fallback msg or some wrong intent is called
