Filtering a HasMany Smart Relationship

Help me!

Here is the code. Mabye request.query.filters can be added to where somehow.

router.get('/user/:recordId/relationships/activity', (request, response, next) => {
  const targetId = `prefix-${request.params.recordId}`
  const limit = parseInt(request.query.page.size, 10) || 20;
  const offset = (parseInt(request.query.page.number, 10) - 1) * limit;
  const recordsGetter = new RecordsGetter(activity, request.user, request.query);

    let where = { [Op.or]: [{ someField: targetId }, { anotherField: targetId }] };
    const findAll = activity.findAll({
        where,
        offset,
        limit,
    });

    const count = activity.count({ where });

    Promise.all([findAll, count])
        .then(([activitiesFound, activitiesCount]) =>
            recordsGetter.serialize(activitiesFound, { count: activitiesCount }))
        .then((recordsSerialized) => response.send(recordsSerialized))
        .catch(next);
});
