I don’t think you know how this works but I’ll explain it to you..
when two people answer your question, there is words in blue that are above the answer to both of them, say “mark as brainliest” you click on one of them to make the answer to your question that someone else answered and then that’s it. So hope this helps
im pretty sure it only appears when a person answers and it takes a long time for someone else to answer or if two people answer you have to choose between the two
