I have installed VSCodium on my Linux instead of regular VSCode or VS

When I right-click on a function, I’m used to getting a “Go to defition”, “Find all references”, etc… But not anymore.

I do have one function that appears in my right-click menu : “Change all occurrences” but it only works for a single file. While I was used to ctrl+R to rename any symbol project-wide

I’m also lacking some informations like the parameters needed to call a function as I’m writing it or the errors getting squiggly red lines through pre-compilation.

I thought that VSCodium is just Visual studio minus spyware ? What happened ?

I was advised extensions which I already have.

Someone had the same problem because the @builtin extension of his programming language was disbaled but mine is enabled.

I can’t find the InteliCode extension.

I feel like there is something really simple which I’m forgetting and that isn’t enabled by default
