FindFirst Config Optional `with`

Hi, I am trying to do something like an optional findFirst config here. i am expecting the resultType of readTemplater would be with relations of templaterResults. but the type is only templaters without relations.

type Input = NonNullable<
    Parameters<(typeof db)['query']['templaters']['findFirst']>[0]
>;

export const readCustomTemplater = async (db: DB, input: Input) => {
    try {
        const res = await db.query.templaters.findFirst(input);
        if (!res) {
            throw newResourcesNotFoundError(
                new Error('Templater not found'),
                templaters,
            );
        }
        return res;
    } catch (err) {
        throw new Error('An error occured')
    }
};

export const readTemplater = async (db: DB, id: string) =>
    await readCustomTemplater(db, {
        with: {
            templaterResults: true,
        },
        where: (field, { eq }) => eq(field.id, id),
    });


However if i change the readCustomTemplater parameter to specifically receive with input, the result type of readTemplater shows the correct type, which is templaters with relations of templaterResults

type WithInput = NonNullable<
    Parameters<(typeof db)['query']['templaters']['findFirst']>[0]
>['with'];

export const readCustomTemplater = async (db: DB, input: WithInput) => {
    try {
        const res = await db.query.templaters.findFirst({
            with: input,
        });
        if (!res) {
            throw newResourcesNotFoundError(
                new Error('Templater not found'),
                templaters,
            );
        }
        return res;
    } catch (err) {
        throw new Error('An error occured');
    }
};

export const readTemplater = async (db: DB, id: string) =>
    await readCustomTemplater(db, {
        templaterResults: true,
    });


but my goal here is to fully let the caller have the control of findFirst config
