DB::enableQueryLog() return undifiend method

I want to log query and get it's sql so I tried:

DB::enableQueyLog();
        Auth::user()->books();
        dd(DB::getQueryLog());

but I get error:

Call to undefined method Illuminate\Database\MySqlConnection::enableQueyLog()"

also tried what suggested in laravel 5.8 docs but nothing get output to screen and when I open the log file there is no sql in it.

please how to log the query and get it is raw sql?
