Adding different payment methods on our React website -- 2

We would like to add the following payment methods on our website:-

1. Google Pay and Apple Pay using Stripe
2. Amazon Pay (optional)

We already have Stripe integrated on our website and working. However, we want these to also be on our website. Additionally want to 3) improve the checkout/payment system cause some payments are rejected by banks. We want all bank card to be able to pay with no errors.

Website: https://peloq.com
Budget: 50-100 €

Here are what we use:-
1. Frontend -> React.js TypeScript
2. Backend -> Express.js TypeScript

We are using these npm packages for handling Stripe payments in the frontend React
"@stripe/react-stripe-js": "^1.7.0",
"@stripe/stripe-js": "^1.21.2",

and in the backend,
"stripe": "^8.201.0",

Read carefully, please don't bind if you cannot cooperate with such simple tasks.
A) You will not speak with me directly I am not the developer of my site. I am only the owner!
Regarding any matters for the site you will speak with the developer.
B) Our website is connected to discord - You will need to create or have a discord account
C) You will be paid FULL (NO 50% payment) only when at least points 1) and 3) from above are completed successfully.

Thanks for cooperation.
