PHPStorm not available

I can’t seem to get the intellij add-on to work. I have turned it on under preferences -> add-ons, however, it is not available at all under utilities, even though am working in a custom environment.

When i open the addons folder, it’s empty. Nothing is there.

I haver tried to install different versions of local but that did not work. Someone pointed out that it might be available in 2.4.3 but that is not the case.

Any idea on how i can get this to work or where i might be able to get another copy of the add-on? I have looked around to download the add-on seperately but i can’t find it and there is 0 documentation on this topic.
