Custom terms of service don't override auto generated terms of service disclaimer as expected.

Describe the bug

I'm not able to override the auto-generated terms of service disclaimer below the checkout button, even though the docs suggest it is possible to override completely.

I tried TermsOfServiceAcceptance, AfterSubmit, Submit. For all of them, my new Message text was displayed alongside the auto-generated disclaimer instead of overriding it. I would like to override it completely, and the docs and comments in the library made me think that this was possible.

If overriding the auto-generated disclaimer is supported, how can it be done?
If overriding is not supported, is it worth updating the docs to be clearer about it?

To Reproduce

Create a checkout session with the code snippet below, adding your own disclaimer string. See that default terms of service disclaimer that is displayed below the checkout button is not overridden, but your own disclaimer string is presented above / below the auto generated text, with the auto-generated text still being present.

Expected behavior

I want to override the auto-generated terms of service disclaimer below the checkout button, the docs suggest it is possible to override completely.

Code snippets

func newStripeCheckoutSession(..) {
    ...
    params := &stripe.CheckoutSessionParams{
        ConsentCollection: &stripe.CheckoutSessionConsentCollectionParams{
            TermsOfService: stripe.String(string(stripe.CheckoutSessionConsentCollectionTermsOfServiceRequired)),
        },
        CustomText: &stripe.CheckoutSessionCustomTextParams{
            AfterSubmit: &stripe.CheckoutSessionCustomTextAfterSubmitParams{
                Message: stripe.String(disclaimer),
            },
            TermsOfServiceAcceptance: &stripe.CheckoutSessionCustomTextTermsOfServiceAcceptanceParams{
                Message: stripe.String(disclaimer),
            },
            Submit: &stripe.CheckoutSessionCustomTextSubmitParams{
                Message: stripe.String(disclaimer),
            },
        },
    ...
}
