Has anyone successfully migrated whatsapp chat history from Android to iphone?

Jul 8, 2022
I've been trying this for the last 2 weeks and just struggling. The move to ios app only moves across the groups that I am a part of on whatsapp but not the actual chat history. I even paid for a third party app (I should have known better), and even that didn't work.
Any clue when normal people like me are going to be able to use the move to iphone feature? I read that they were rolling out the transfer option from 14 Jun 2022, but unsure whether that is only the beta or whether that is a formal feature.
Also, any idea whether using a lightning to usb-c cable and linking both phones up would serve any purpose in helping with the migration through some other method?
Thanks in advance
