typeorm QueryBuilder: how to match column value of boolean?

Question

In Typeorm Query Builder, what is the syntax like when I want to match rows whose value is equal to a boolean of True?

For example, I have this working code:

  await getConnection()
      .createQueryBuilder()
      .delete()
      .from(Notification)
      .where("id = :id", { id: 1 })
      .andWhere('dstOrgId = :dstOrgId', { dstOrgId: 1001 })
      .execute();

However, if I want to match all rows whose clicked column has a value of boolean True, how should I write it?

I want to do something like:

  await getConnection()
      .createQueryBuilder()
      .delete()
      .from(Notification)
      .where("clicked = :x", { x: true })
      .andWhere("viewed = :x", { x: false })
      .execute();

But this above code does not seem to be in nice syntax, or "proper" syntax
