How to send multiple variable in laravel mailuse function

I would like send $leads, $target, $hello variables to view emails.report

  \Mail::send('emails.report', ['leads' => $leads], function ($m) use ($leads, $target, $hello) {

when i just do

\Mail::send('emails.report', ['leads' => $leads], function ($m) use ($leads) {

it works,

when I send more than 1 variable in use function it doesn't work. How can i send multiple vars ?
