OP 4P battery handle

I have another question regarding my pre-ordered DJI Osmo Pocket 4P. Unfortunately, I can't find any information on this. When I check DJI here, there is no information on the 4P yet.
 
The VLOG Combo comes unfortunately without the additional battery handle 😩, but since I need the camera for a trade show, I require that extra reliability. I also need to be able to connect USB-C headphones to the Osmo Pocket to monitor audio. Something that works perfectly with the original battery handle of the OP3 but with almost no third-party battery handles.
 
Is the original DJI battery handle the same for the 4 and the 4P? Or is there another original DJI battery handle that I can or should use?
