Hi @omar2205,
thank you for your interest.
Please make sure that you have followed the installation instructions carefully.
Here you can find the further installation steps for Google Sign-In.
If you want to use the Firebase JS SDK, please have a look at this guide.

This plugin uses the getAuth() method of the Firebase JS SDK. You do not need to pass an object.

}
