When I disable the embed, the checkout page is not found, Here is what the parameters look like

await createCheckout(
        config.lemonsqueezy.storeId,
        variantId,
        {
            productOptions: {
                enabledVariants: [variantId],
                redirectUrl: `${config.siteUrl}/request-access?session_id=${session_id}`,
                name: plan
            },
            checkoutData: {
                "email": "tita0x00@gmail.com",
            },
            checkoutOptions: {
                // todo: when false, checkout page is not found
                embed: false,
                media: true,
                logo: true,
            },
            testMode: true,
            expiresAt: null,
            preview: true,
        },
    )
