Anyone know if the IRS plans to send out a notice to taxpayers in early 2022 who received the advanced child tax payments in 2021?

I have zero interest in asking my 1,000+ clients if they authorize me to set up an IRS account or to access their info - too much of a hassle. Wish IRS made it simple to get the info (think GET MY REFUND where you only need a few pieces of info)
