Send and receive data to and from a website using the TWebbrowser component in Delphi

I'm creating a VCL Application with Delpi 10.3 and want to support some web functionality by having the user enter the ISBN of a book into a TEdit component and from there passing/sending this value to a search field on this website: https://isbnsearch.org after which the website looks up the ISBN and displays the Author of the book. I want to somehow access the information (i.e Author) presented by the search result and again use it in my application.

This is my GUI, for a better idea of what I want to accomplish:

What code can I use for this? Any other feasible suggestions or approaches are acceptable.
