Relational query `extras` are not properly adding sql

const data = await db.query.user.findMany({
    columns: {
        id: true
    },
    extras(user, { sql }) {
        return {
            loweredName: sql`lower(${user.firstName})`.as(
                "lowered_name"
            )
        };
    }
});

const data = await db.query.user.findMany({
    columns: {
        id: true
    },
    extras: {
        loweredName: sql`lower(${user.firstName})`.as("lowered_name")
    }
});

select "id", "lowered_name" from "user"

select lower("user"."firstName") as "lowered_name" from "user"

await db.query.users.findMany({
    extras: {
        loweredName: (users, { sql }) => sql`lower(${users.name})`.as('lowered_name'),
    },
})
