How to specify the language of the checkout page when using the JavaScript Buy SDK.

Hello, Shopify Forum members.

I have a question regarding how to specify the language of the checkout page when using the JavaScript Buy SDK for checkout.

In the past, appending ?locale=en to the webUrl of the checkout object would redirect to an English checkout page. However, it seems that this method no longer works.

Is there currently a way to specify the language of the checkout page when using the Shopify Buy module?

Thank you for your assistance.
