Canon seems to have stopped making battery grips for the Rebel series cameras starting with the T7i and 77D. Third party battery grips starting showing up for these cameras not long after they were released.
Unlike previous cameras that had optional battery grips, these cameras have no electrical contacts for the shutter in the battery compartment to allow for a vertical orientation shutter button. The third party workaround is to supply a short cable that connects to the remote shutter connection.
I expect you might see a third party grip for the 2000D and 4000D, but they have been out for awhile now, and there have been no third party grips produced as of today.
The 4000D is an entry-level DSLR and therefore will not have the ability for more advanced things. If there is no Canon brand battery grip for it, there is no grip. No grip that you should even try to use. None!
I agree with Erne. You do not want to try use one of these grips on a camera not designed to use one. You will not have the advanced things, like a simple wheel to adjust the shutter speed, for example.
