    This script will add HttpLoggingInterceptor at OkHttpClient, so
    the HttpLoggingInterceptor will print all requests and responses.

    This strategy does not matter if you are doing TLS Pinning bypass 

    Run with:
    frida -U -f [APP_ID] -l okhttp-logging.js --no-pause
    or
    frida --codeshare helviojunior/okhttp-logging -U -f [APP_ID] --no-pause
