Autocompletion is not aware of my custom type's members

[KRC2000]

I am just starting out with using neovim and this plugin, please help me. I installed coq_nvim, its working, all is good but one thing. I created a simple c++ program, there is a custom class "Meal" with a public variable "calories". When I type "." after a object name, I want to see suggested all the members of that object, in my case "calories" variable, but it is not happening. Is that possible with this plugin? Can I achieve that? Thanks.

Here is what I see when I hit <c-space>

It's a lot to unpack here. Have you configured any LSP Server (like ccls) to work with your C++ project? If not I suggest you to take a look at nvim-lspconfig first.

Coq_Nvim does not analyze your code base it just queries multiple source of completion (like LSP, Treesitter an so on)
