Export Macros with base64 PNG

We have a web application, the administrator record a script and save on
our application, and a user started the application on a WEB page.

We can started the kantu by webpage and pass the script. But we can´t
pass the thumbs of the xclick targets. (is it possible to pass the
thumbs by base64 or URL ?). How can I do that ?

is it possible to pass the thumbs by base64 or URL ?

Not yet, but this feature will be available soon.
