.env files inaccessible in macos

I have a .env file mounted in MacOS (Sequoia). I'm able to access it in the terminal and it behaves as expected, but I cannot get it to show up in Finder or file dialogs. This matters because I'm trying to use it in an Intellij Idea run configuration, which uses the OS file selection dialog to select environment files and doesn't allow specifying those file locations explicitly. 

Even if I save it without the `.` prefix, it still doesn't show up. Other ".whatever` files are visible, as well as zero length files, so I gather that named pipes are just generally not supported...? 

I hope that I'm missing something, because this does not seem to be niche use of this technology, but I haven't run across any indication that anyone else experiencing this problem. Is there a workaround I've missed? Is no one actually using .env files for development in this very popular IDE on this reasonably popular OS?
