iPhone Apple ID setting keeps asking to update my WatchOS which is no longer supported by Apple

I use first generation of Apple Watch with watchOS 4.3.2, the last watchOS supported by Apple. Recently, Apple keeps asking to provide password through Apple ID Suggestions on my iPhone 13.

Every time after keying in password, the message:

Software update

required

Update this Apple Watch to

the latest version of

watchOS to sign in.

This Apple Watch no longer supported by Apple is not compatible with later versions of watchOS let along the latest version.

How to disable this annoying message by the iOS asking me to do impossible thing?

any way to disable this annoying message?
