Required Research for Biochemistry Majors

I am a first-year biochem major and I am lost on how to find a research position and how the process works. I know that I will need to cold email a bunch of professors who are doing research and hope they say yes. But after that how does the process of adding the research to your course load work? Idk if this makes sense but if any fellow biochem majors can share their experience with the required research it would be highly appreciated!
