I use Snapchat on my computer, and sometimes I want to save my friends' jokes. I solved one problem. I don't know why it wasn't solved right away. And one of the main functions of Snapchat is that the transmitted images and messages are available to the recipient only for a short time before they become completely inaccessible. That's why I put myself a screenshot tool on Chrome. It's a great extension, and it has Capture single web elements so you can save it to yourself right away and not be lost and even create Gifs. Maybe someone will be helpful.
