@Kabirdas Couldn't make your app work for me. I set up the API on Adobe website, added retool-edge.com as allowed domain, pasted the API key in textInput2, but the component always returns This application domain (https://retool-edge.com) is not authorized to use the provided PDF Embed API Client ID.
It still requires a lot of boilerplate vs. just passing the pdf to the browser to handle natively.
Why going through a component ? Which btw I feel would not work if browser must prompt for Basic Authentication.
