Announce the availability of Apple Pay In-App Provisioning

Hi! Can someone tell me please, over what period or how many times should the splash screens/interstitials pop up after login? Is it possible to limit the number of times these splash screens/interstitials are displayed for each card, or is it mandatory to display them all the time? In "Getting Started with Apple Pay In-App Provisioning" find only this phrase "Announce the availability of Apple Pay In-App Provisioning to users. Encourage new users to get the most from their card through the use of splash screens/interstitials or clear calls to action" Thanks!
