Why aren't previews shown in Telegram when sending using the "copyMessage" method?

Question

Node.js

I'm using the copyMessage method from npm Telegraf.
The message is forwarded, but if it contains a link, then there is no preview. Are there options to somehow indicate that a preview is needed?

Answer 1

So, if anyone is interested, in addition to the actual text, the message object contains an enumeration of additional entities, such as hashtags and links. Depending on the message type, the property is called either "entities" or "caption_entities". It also needs to be passed on.
