Obfuscate expo app ? any experience ?

How to obfuscate the app build in expo ? whats the step ? I tried to google but wasnt clear and not a lot of infos, mostly ony obfuscating pure rn.

do i have to obfuscate everytime before ‘expo publish’ ? or before build apk/ipac ? if i obfuscate before apk, then when i publish again… it shouldnt be have any problem right ?

does obfuscate include encrypt the javascript ? or only native code ? i don’t need to eject to obfuscate right ?

what kind of common problem after obfuscating ? is it okay to not obfuscating the app for playstore and apple store? i dont have any secret key but a lot of url inside
