Stripe payment SCA - php

Question

My current Stripe code is as below: as I pass to stripe.
Had been using following Stripe Library:
https://github.com/stripe/stripe-php
Its working fine as of now. Now I need to change code according to SCA. But I am total lost with code update.
My controller
$this->stripe_->add_charge_array($stripe_user_id, $order_info, $price * 100, $currency, $metadata);
$this->stripe_->pay($currency_id, , $stripeToken, $card_id);
$data = $this->stripe_->get_charge_response($stripe_user_id, , $order_id);
$order->setStripeChargeId($data['charge_id']);//Here I save to db
And in stripe library:
public function pay($currency_id, $stripe_token = null, $card_id = null, $account_id = null){
$charge = $this->charge_card($cart['amount'], $cart['currency'], $stripe_token, $description, $cart['metadata'], $currency_id, $account_id);
}
And my charge_card method connecting to Stripe
public function charge_card(){
try {
\Stripe\Stripe::setApiKey($STRIPE_KEY);
$charge = \Stripe\Charge::create(array(
"amount" => intval($amount),
"currency" => $currency,
"source" => $stripe_token, // obtained with Stripe.js
"description" => $description,
"metadata" => $metadata
));
} catch (\Stripe\Error\Base $e) {
// Display a very generic error to the user, and maybe send
// yourself an email
$result = self::put_stripe_error($e);
} catch (Exception $e) {
// Something else happened, completely unrelated to Stripe
self::put_stripe_error($e);
}
return $charge;
}
Stripe library:
https://js.stripe.com/v3/
From what I did understand from documentation is that I need to change my charge_card method like below.
$intent = \Stripe\PaymentIntent::create([
'payment_method' => '{{PAYMENT_METHOD_ID}}',
'customer' => '{{CUSTOMER_ID}}',
'amount' => 1099,
'currency' => 'gbp',
'confirmation_method' => 'manual',
'confirm' => true,
'setup_future_usage' => 'off_session',
]);
But then I get payment method Id in $intent . How to proceed from here.
Documentation misses this.
