I used $ssh->login instead of $ssh->run_ssh(2). 
#!/usr/bin/perl

use strict;
use warnings;
use diagnostics;
use Net::SSH::Expect;

my $ssh = Net::SSH::Expect->new (
          host     => "host",
          user     => 'user',
          password => 'password',
          raw_pty  => 1,
          timeout  => 5
);

        
eval {
         my $login_output = $ssh->login();
         if ($login_output !~ /Welcome/) {
             die "Login has failed.
             Login output was $login_output";
     }
};
        
$ssh->exec("stty raw -echo");

my $whoami = $ssh->exec('whoami');
    print $whoami, "\n";
       
my $ls = $ssh->exec('ls -l /');
    print $ls, "\n";
