To display the inline keyboard, it is necessary to add the "Message with keyboard" block in the script.
In the advanced editing of the block, enter the text of the message and add the necessary buttons. And also check the checkbox "Inline keyboard (Telegram and widget only)"
In order to click on the button to go to the link, you need to:
{
"ActionType": "open-url",
"ActionBody": "[<https://www.google.com>](<https://www.google.com/>)"
}
where the ActionBody specifies a link to the site.
When clicking on a button with a link to a site, a pop-up will open, asking whether to open the link, and the name of the site specified in the Json configuration of the block.
Links can only be specified for inline buttons
