Unable to access Whatsapp on Macbook

New Iphone SE (2022 Version) Purchased from Apple Store Bangkok Thailand February 2024

Didn't set up touch id. Didn't need it. But now Whataspp for Macbook on browser no longer linking to iphone Now need to use touch id to link but cannot as says need to authenticate to be able to add fingerprint.

No way to authenticate. Phone is only 8 months old. Clean. But now unable to continue to use Whataspp on my laptop as the phone is clearly not working. Reading the community notices I see lots of other people have same problem. What's going on? Can anyone help.
