Transfer WhatsApp videos

Transfer of WhatsApp was part of the Sony setup new phone process between old and new Sony phones. It did it without asking me.

My chat is all on the new phone with all the images as well, but the videos that were in  some of the messages have completely disappeared.

The transfer used Google and all my images are in google but I can't find the videos. Whatsapp is no longer on my old phone since the transfer.

Is there any way of getting my videos back?
