How to make vscode complete code for Unity?

Question

Unity

Hello!
Recently I wanted to make games. I must say right away that I have Manjaro KDE Plasma 5 (Linux).
At first I made them in Godot Engine, but I didn’t like it, so I downloaded Unity and vscode, respectively.
Installed extensions in vscode: C#, Tools for Unity, Debugger Unity, Unity Snippets.
In unity itself, I went into the settings and connected vscode as a code editor.
But when I want to create a new c# script, I double-click on it, vscode opens;
I immediately see that the word MonoBehaviour is an unknown word, but when I want to write any word, for example, transform, it does not complement it (for example, I write trans, it should give me a small menu with matches, but no! who understood , he understood), and if I write the name of the method (Awake (), Update () and others), then it complements it (as I later realized that this is due to the above extensions).
I want vscode to complement words, data types and TD (I'm talking about transform, GameObject, public, private and TD)

You also need a C# add-on.
But I recommend taking Rider - it has many more functions for the unit and everything is set up at once.
