Asking for the job at the end of the interview

My entire fyp is just a bunch of of career coaches and recruiter influencers. Some of them suggest asking the hiring manager or whoever to ask for the job by asking based on our conversation what gives you pause about bringing me on board or something. Does this actually work m? I’ve used it maybe 3 times years ago and haven’t used it since. I don’t like it because it puts the hiring manager on the spot and they can just lie and say no and then the conversation ends in an awkward way
