I am currently facing a problem while using WebStorm with TypeScript v3.7.5. In this particular version, TS introduced the `??` operator. I have implemented it in my project but it seems like WebStorm is not able to understand it and displays an `expression expected` error. Surprisingly, when I run the `tsc` command, no errors are shown.

When I open the code in VSCode, there are no errors visible, so I believe the issue does not originate from my TypeScript configuration.
Is there anyone who knows the reason behind this behavior and how to resolve it?
