Problem after failed synchronization of Whatsapp between Android and Iphone

[Android Central Question]

Dear Sirs,

I have a problem with my current Iphone installed whatsapp
If possible, I would like some help
Since about a year ago, I had an Iphone.
Later on, I switched to an Android Phone and I used this new android phone moving my telephone number from the old Iphone to the old android
Since I had all my whatsapp messages in the Iphone, I kept using the Iphone only for whatsapp using WiFi
I did not have any telephone number connected with the old Iphone
Unfortunately, I broke the screen of th Old Iphone a few days ago and while trying to check my whatsapp I decided (most stupid decision) to see if I could see my messages using the new android
So I tried to install the whatsapp in the new android with the same number of the Iphone
What happened is that I found out that the messages in the Old Iphone have now been apparently deleted as the Whatsapp number is not connected to the new phone
I went to change the screen of the Iphone a while ago and now it works fine
Unfortunately, I have created a new problem and now when I click on the whatsapp button in the old phone it looks like there is no file left
I am pretty sure the files are stored somewhere in the Iphone since I have not deleted anything but I have no clue about how to restore them or, at the least,
to see them so that I can move them (movies, photos, conversations and numbers) to my laptop
I would appreciated your help

Being that I closed the contract with Apple a while ago, Whasapp was working on the old Iphone but I had no backup whatsoever

Regards

Matteo
