I have just installed PHP IntelliSense v2.3.14 on
VSCodium (AppImage build) for Kubuntu 21.04
On the system $PATH is PHP 7.4.16

When I load up a Symfony project or any other PHP project
When I try and go to a definition I see a tooltip saying : No definition found
When I go to Runtime Status I see
Not yet activated.

What am I not doing right?
