Thanks! As mentioned in another comment, currently there is no build in support for this yet.

As a workaround one could use a service like ScrapingBee (not affiliated) as a proxy, that renders the page in a browser for you.

Surely, relying on a service for this is not always ideal. I am also working on a small wrapper that turns Chrome into an HTTPS proxy, which you could plug right into flyscrape. Unfortunately it is very experimental still and not public yet. I have not yet decided if I release it as part of flyscrape or as a separate project.
