What does a UX designer do?

As a curious individual delving into the world of tech and design, I find myself wondering: What precisely does a UX designer do? Are they solely responsible for creating visually appealing interfaces, or do they delve deeper into ensuring a seamless and intuitive user experience? Do they collaborate closely with developers and product managers, or do they operate independently? Furthermore, how do they stay abreast of the ever-evolving trends and technologies that shape the landscape of user experience design? It's clear that UX designers play a crucial role in shaping the way we interact with digital products and services, but I'm eager to gain a more comprehensive understanding of their responsibilities, skills, and the impact they have on our daily lives.
