How do I update a boolean field to its opposite in Mongoose?

Question

So I have this function:

async function update_subscription_status(id) {
    await User.updateOne({chat_id: id}, {
        mailing: // need to change this boolean field to its opposite       
    })
}

Is there any way to do it without checking its state before updating?

Use update-documents-with-aggregation-pipeline

$set

$eq returns true or false

async function update_subscription_status(id) {
    await User.updateOne(
      { chat_id: id },
      [ { "$set": { "mailing": { "$eq": [false, "$mailing"] } } } ]
    )
}
