I'm considering trying out PDFKit at work next week. I just took a look at the documentation and it looks really well detailed.
Please do let me know if you are able to get it to work - I'll keep you in the loop as well!
Chiming back in to confirm that for now this is still something that can only be handled via creating a custom component and/or using a third party library.
We've seen interest in this from customers over time, and have been tracking a feature request internally for something like a "PDF parser" component to, for example, parse text from a PDF and return text/JSON. If I'm understanding the above use case right, if implemented, that feature could potentially address this request!
I'll move this to our Feature Request category so others can follow along/chime in with interest in this feature for our product team's consideration.
