Unity Sign-in Authentication with Google Firebase 2024

So, I was learning how to set up Google authentication with Firebase in Unity and decided to make this video for myself for future reference. When I forget how to do it, I can watch this video again. I also hope this video helps you guys too.
I can't answer all your questions because I'm still learning as well, but you can use my method. I faced many issues before I was able to build and run it smoothly by looking for solutions on Google, Stack Overflow, GitHub issues, and even asking my brother ChatGPT.
