Beginner needs help: Load random static mesh at runtime

Hi. I want to randomly select a static mesh blueprint actor and display it at runtime. Eventually, I want to loop through hundreds of these but first I need to take a step back and learn how to do one. I have scoured the Internet and I have seen several people ask this question. But I am a complete beginner and I am unable to get any solution to work (I don’t understand all of the terms yet). Would someone please create a sample graph of this solution and tell me the steps?
