Stripe payment integration

We have an Stripe elements payment integration on our php based website, but the integration it's old, doesn't accept 3D secured payments and we need to upgrade the Stripe php library with the new one and from here we have two options: 1. Update the library and migrate the currently integration to Stripe payment Intent using this documentation [login to view URL] I attached the file that needs to be migrated to take a look. 2. Update the library, scrape the code of the existing integration and integrate the Stripe checkout from this video, literally you just have to copy paste from this video: [login to view URL] and after that you need to implement the part from the file [login to view URL] the part with if($charge) that checks if the payments it's successful and updates the data base by adding credits to the user or premium. I will provide the documentation and where the code it's placed for easy access.
