How to configure vscode not to show files that I open in the editor in the sidebar?

Question

Visual Studio Code

Good afternoon.
Now, if I open a file in the editor via ctrl+p, it automatically gets focus in the sidebar.
In this case, if the project is large, then a tree with files opens.
How to prevent this behavior?
I rummaged in the settings, but could not find such an option.
Thanks in advance.
