Try Now button is not showing on published play store application having Instant app feature enabled

I have updated my current play store app with the Instant app feature enabled. But it is still not showing the "Try Now" button after waited for 5 days.

I have implemented an instant app feature in a current app and updated it like below:

1. added a dependency in app-level Gradle: implementation "com.google.android.gms:play-services-instantapps:17.0.0"
2. To enable instant app right-click on app module -> Refactor -> Enable instant app support.
3. Increment a version code to 1 and uploaded a new build on the play store.

Could you guys please help me out to find out the missing element or a direction?
