I have such a code, it is a response from websocket after performing some action on the page, I would like to dig into how it is executed and decrypt this code.

I have tried programs to decrypt obfuscated code online, but nothing is able to decrypt. Is anyone able to step-by-step how to go about decrypting, what programs to use, etc.?
