Running PhpStorm VM instead of IDEA to Test Plugin

Hi,

I'm trying to test a plugin locally by running it in PhpStorm (I was previously running it in IDEA).

I've added "-Didea.platform.prefix=PhpStorm" to the VM Options, as well as adding php and php-openapi under Project Structure > Dependencies and set them to Provided.

However, I'm currently getting the error "Resource is not in classpath or wrong platform prefix: PhpStorm". I've tried putting in the absolute path to PhpStorm.app to no avail.

Thanks in advance!
