How to run vscode extension command just right after installation?

I need to run the extension command right after the installation. There is an event like onStartupFinished, but the problem is, it will run every time the vscode starts.
How to do it? does vsocde have any way to do it?

>Solution :

You can use a version field in the global context state. You get the context in your activation method.

export const activate = (context: ExtensionContext): void => {
    const myExtension = extensions.getExtension("<my-extension-id>");
    const currentVersion = msgExtension!.packageJSON.version ?? "1.0.0";

    const lastVersion = context.globalState.get("MyExtensionVersion");
    if (currentVersion !== lastVersion) {
        void context.globalState.update("MyExtensionVersion", currentVersion);
        // Do one time setup here.
    }
}

Don’t forget to set onStartupFinished in activationEvents.
