-   If you don't pass any of those parameters, the default behavior unlocks the feature only if tier 1 is purchased and shows a paywall on press if tier 1 is not yet purchased. If `showPaywallOnPressIfLocked` is set to `false`, the locked view will not have any automatic interaction, just rendering locked view state as-is without any added behavior.

    > Note: If you place `PaidFeatureButton` or `PaidFeatureView` inside a view that self-dismisses itself after any interaction (like in a `Menu`), the paywall might not show because SwiftUI deinitializes the view and attached logic before it can be executed. Use the below method in such contexts and place the `.paywall` modifier at the root of your view to avoid auto-deinit.
