Help! I want to transfer chats from my IPhone 14 pro max to my Samsung Z fold 7

Hi there

I have used iPhone all my life. I always back up my WhatsApp chats to my c Icloud. I have been using my new z fold for the past few months (using WhatsApp signed in as a companion to my iphone) but I now want to get rid of my iPhone so I want to be fully logged in to my z fold WhatsApp with my current number. But I want all my chats remaining as they go back to 2019.

How do I do this please? Any recommendations would be much appreciated. Thanks 😊
