I host WebView2 in my vb6 app using RC6. I would like to call CallDevToolsProtocolMethod Page.printToPDF and get the base64 of the pdf back, but I believe the current version of RC6 does not provide a return value when calling CallDevToolsProtocolMethod, probably because it is async. I tried to check the various events but none trigger, so it seems there is no way to get the return value from CallDevToolsProtocolMethod Page.printToPDF.

Any ideas?
