If you're using local app clip experiences to test those do not support displaying the smart app banner in Safari. They only work to simulate QR and NFC invocations. If the smart app banner does show up for a local experience today, that's unfortunately a bug. Our supported methods for test invocations are documented in Testing Your App Clip’s Launch Experience - https://developer.apple.com/documentation/app_clips/testing_your_app_clip_s_launch_experience, and please file feedback for things you'd like to see in the future.
