PHPStorm window.showOpenFilePicker() unresolved function
I am working on a very basic website to upload JSON files, edit them and then download them. I followed this description: https://web.dev/file-system-access/
Sadly, I get the problem "Unresolved function or method showOpenFilePicker()" (as you can see in the screenshot). I am quite a beginner with javascript, but I do understand that it doesn't find the method.
But the "window. object" should have this method available? I am truly confused. Do I need to install some other module?
Thank you very much for the help! If you need any further info, I'll gladly add them.

library definitions the IDE uses for WEB API types resolving are provided by Microsoft (https://github.com/Microsoft/TypeScript repository); PhpStorm doesn't have its own library definitions. And the property 'showOpenFilePicker' does not exist on type Window in https://github.com/Microsoft/TypeScript/blob/master/lib/lib.dom.d.ts
Ok, thank you for explaining that!
So how can I still include this method in my program? Import the file system API somehow? https://developer.mozilla.org/en-US/docs/Web/API/File_System_Access_API
What else would be the proposed way of opening a JSON file?
I don't think this can be fixed on your end, you can only suppress the error (https://www.jetbrains.com/help/webstorm/2021.1/disabling-and-enabling-inspections.html#suppress-in-editor)
