How to distinguish deep links that are incomplete so that the app does not handle them?

[SametSahin10]

Hello. I have a question about this part in docs:
https://docs.walletconnect.com/walletkit/ios/mobile-linking#ios-wallet-support

Additionally when there is a signing request triggered by the Dapp it will hit the deep link with an incomplete URI, this should be ignored and not considered valid as it's only used for automatically redirecting the users to approve or reject a signing request.

How can we distinguish the deep links that shouldn't be handled by our app? When is a URI considered incomplete?
