getting stripe terminal and Wordpress working

I have a plugin that I want to add stipe terminal to it as a tab to checkout customers. The plugin has a widget that looks exactly how I would like the checkout to be with stripe. Instead of hitting the button to book appointment it create a payment intent with stripe. I have everything working already with receiving payments on the terminal but I do not know jquery so I do not know what to copy to duplicate the widget code to get the look and functionality. Then change the button post intent. Please reference https://github.com/stripe-samples/terminal/tree/main/server-driven before bidding.
