Microsoft Edge and Adobe partner to improve the PDF experience

Hello,

I have PDFs with valid signature if open them in acrobat reader app, but if I open the same PDFs in Edge (or EdgeWebView2) with Adobe Acrobat PDF engine, the signature is displayed as invalid. 
Acrobat reader mention that the source of Trust to validate the signature is European Union Trusted List (EUTL). (trust service "DigiCert Europe Belgium B.V."
Would it be possible to add this source of Trust for Edge (and Edge WebView 2) either out of the box or provide a way to configure that on our side. (for both Edge and Edge WebView2)

Having the explanation why the signature is considered invalid/valid/unknown would be important as well.

Thank you
