The initial trigger is as mentioned above, but there is one thing you must pay attention to when going out to the mine to find hidden miners. Before talking to the hidden miners, do not click on other miners except the hidden miners. If you talk to them first, it will be in vain, because if you click on other miners and talk to them, all the miners will be gone, which means that the hidden miners have also left, and you said to jump on, there are several miners. When going in and out of the mining area, press alt+left click to easily jump onto the wooden frame. At the end of the wooden frame, on the mountain, is where the hidden miners are.
