Utilize the onReady Handler:
The important addition here is the onReady handler. This function is called whenever the script component mounts, ensuring the script is ready to use every time navigation occurs.

When you navigate using the Link, the script is fetched and loaded as expected because of this handler.

Integrate into Your Components:
Ensure that your component where the Google sign-in button is implemented listens to changes in script loading.

Benefits of Using the onReady Handler

Enhanced Reliability: An onReady handler guarantees that your scripts are loaded every time the corresponding page is visited through navigation, not just on the initial load.

Improved User Experience: Reduces instances of broken functionality or errors in your application, resulting in smoother interactions for users.

Cleaner Code: Utilizing the built-in handler minimizes the need for additional complexity in your code.

Conclusion

This method ensures that your Google sign-in script (or any other external script) is seamless in operation, no matter how users navigate through your app.
