Hide Nextjs code in the static chunks

Summary

Secret keys in the CSR gets exposed while using environmental variables and Javascript Obfuscation

Additional information

Hello everyone , 

I have been Nextjs 14.0.2 for my project. I use env files and i works good in the SSR, but in the CSR the variables that I used in the vercel are directly exposed in the chunks files of the source .
Even debugger can show the keys i used.
I need to do javascript obfuscation or hide the confidential data showing in the chunk.
Need a good guidance for sorting out this issue.

Thanks in advance.

Can you explain, maybe with pseudocode, the kind of sensitive/secret data, and why it ends up in the client, and if so, why is it needed there?

like I write some specific key or user id , hardcoded in the project ,in order to control the action within code itself . By doing so , during production build , they get stored in the chunks of static in the sources. This is my problem , I need to hide this from the general users
