[Ishoshot]

just in case you're having this issue also. From the code above, it is evident that vendor/ichtrojan/laravel-otp/src/Otp.php:29) is where to go.

You'll likely find

$token = str_pad($this->generatePin(), 4, '0', STR_PAD_LEFT);

if ($digits == 5) $token = str_pad($this->generatePin(5), 5, '0', STR_PAD_LEFT);

if ($digits == 6) $token = str_pad($this->generatePin(6), 6, '0', STR_PAD_LEFT);

You can just create new instance of Otp and then can access its property generatePin

Like this

$token = str_pad((new Otp)->generatePin(), 4, '0', STR_PAD_LEFT);

if ($digits == 5) $token = str_pad((new Otp)->generatePin(5), 5, '0', STR_PAD_LEFT);

if ($digits == 6) $token = str_pad((new Otp)->generatePin(6), 6, '0', STR_PAD_LEFT);

Thanks @Ishoshot for this contribution.
For performance, make generatePin static i.e
private static function generatePin
and replace
$this->generatePin or (new Otp)->generatePin
with:
self::generatePin

Thanks, and Spot on @okedialf..
