I wanna use and x key when editorfocus and in the vim-normal mode to open vscode extension bar just like the hotkey ctrl + shift + x does.How do I make this work ? The following is my settings.

Expected when I press the and x key.

Use this :
{
"before": ["", "x"],
"commands": ["workbench.view.extensions"]
}
in setting.json.
And use your own keymap to return to the editors
