Key_box issue in wv dumper

[nana]

First of all, I rooted my samsung j400f android phone "Android 8"; after that I started frida server with wv dumper and the folder appeared in wv dumper was "key_boxes".
I searched in the forum threads and what I have found as a solution was to install "liboemcrypto disabler" module in magisk, I successfully installed it and it worked changilng l1 to l3, I tried the dumper again but the same issue found.
After that, I extracted the libwvhidl.so file from my phone using root manager but I wasn't able to find "oemcrypto_le" to paste the "gibberish" above it in script.js, I have searched for this problem in videoforum threads but I couldn't find a solution so I started a new thread
So Anyone can help to find a solution for that and make the dumper generate private keys instead of key_boxes
Your help will be so appreciated

You can run "nm -D libwvhidl.so | grep ' T ' | awk '{print $3}' | grep -v '_'" to get the list of functions. You can ignore:
