What are examples of “sin that does not lead to death” in 1 John 5:16–17?

In 1 John 5:16–17, John distinguishes between “sin that leads to death” and “sin that does not lead to death”: >If you see any brother or sister commit a sin that does not lead to death, you should pray and God will give them life. I refer to those whose sin does not lead to death. There is a sin that leads to death. I am not saying that you should pray about that. All wrongdoing is sin, and there is sin that does not lead to death. (NIV) What are some biblical or practical examples of sins that would fall under the category of “sin that does not lead to death,” and how should Christians approach them in prayer and fellowship?
