based on my 2020 tax guide by Thomson Reuters. it in effect says as long as the use of the space as an employee is for the convenience of the employer the exclusive use test is met. what it does not clarify is whether or not you take 100% of the Home office expenses or must prorate them based on your self-employment use to total use. if I had to guess, since employee expenses are no longer allowed, you would have to prorate.
