Need Assistance with Meta Deferred Deep Link in Android

I am running an App Campaign on Meta and I want to redirect users on a specif screen based on ads they click, so I want a deferred value. I have implemented FacebookSdk and using this function 'AppLinkData.fetchDeferredAppLinkData' but always getting null. For DDL, I tried entering URL, Custom Schema and DDL from a third party but nothing worked out.

Note: You don't need to implement it, I just need your assistance in implementing if you have any prior experience working with the same issue.
