Migrate from iphone to samsung

Hello

I did transfer everything from the iphone with the smart switch but no chats are moved. So now I have a fully installed Samsung s24 and would like to start using whatsapp on it. The chats are not synced for sure, about the contacts I'm not sure. When setup in the iphone again then everything is there. I tried putting the cable but the sync is random, there are a lot of chats missing or just there in old state from months ago.

How do I get the chats there?
