Adding payment source on stripe to link with Squarespace

Hello
I have a Squarespace website and would like to offer Klarna via my stripe payments account.
I have enabled Klarna on my stripe account but need a developer to integrate this making a klarna source, a source object needs to be created using either Stripe.js or the API [0]. Using either method, Stripe returns a source object containing the relevant details for the method of payment used. klarna will also require a statement descriptor before the customer is redirected to authenticate the payment. By default, your Stripe account statement descriptor is used[1].
