Hello, @user39286 
We’re currently working on the option to train the bot using YouTube videos and send them in the chat - Train bot with YouTube videos and make the bot share videos during the chat.
Does this option work for you or would you like to use the videos just from your device (not hosted on any platforms0?
As for sharing links, the bot is capable of doing this and I’ll be happy to check what goes wrong in your case.
Could you please share the following:
-
example of the question and answer where the link should be used
-
source where the link should be pulled from (specific web page, file, etc)
