Edge: Opening several files at the same time

Hi

With my team we're developing a new web application with news technologies (Angular 9, Java 11 + Spring) and we want to know, with Microsoft Edge, how to open several files (Word files) at the same time. We have many URLs linked with our files on a WebDav Server and at the end of our Angular process, we would like to open all these files automatically and all at the same time.

From now on, only one file is oppening.

I look forward to receiving your reply.
