Android Question How to read and display pages of PDF file in B4XPages

I want to read and display pages from a pdf file in my B4XPages app.
I have searched the forum and have found various references to PDFRenderer but can't see which library that is in or whether it applies the B4XPages. Also, seen an example with a
Dim abc as PDFDocument but that gets highlighted as a unknown type.

Can someone tell me if this is possible and if so, how to do it?

Thanks
Phil
