C++ obfuscator

Hello! I am interested in the issue of protecting the code from hacking.
Do you protect your code from decompiling and hacking?
Why did the question arise? I worked in a team that developed games for Android. They all used obfuscators! So almost no one could hack their application.
Now I am interested in the topic of code protection. I looked at the existing topics, they are slightly outdated (8-10 years ago were relevant).
Use / not use obfuscator? Which to choose?
