How to find out which extension provided the command in vscode?

Question

I'm clueless what feature came out of which extension, is there a way to have its source displayed?

Also would be interesteed to know if its possible to trace the source code of the features.

The only thing I can think of is checking the package.json files, as even vscode.commands.getCommands() only returns plain strings. This can be done with the vscode.extensions API:

import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
    setTimeout(() => {
        for (const extension of vscode.extensions.all) {
            let commands = extension.packageJSON.contributes?.commands;
            if (!Array.isArray(commands)) {
                continue;
            }
            for (const command of commands) {
                console.log(command.title + " is from " + extension.id);
            }
        }
    }, 2000);
}

Note that all only includes activated extensions, hence the timeout to make sure all extensions that activate on startup are done with their activation.
