How to use Mini Program live-play and view-cover together? I don't understand. Can you give me a code example?

live-play always blocks the like button and wants to put the click button in front of live-play, but doesn"t understand the use of view-cover?

this picture of school supplies on the simulator is on live-play, but it will be overwritten by live-play on the real machine.
