Which is why you'll get better at estimating as you get more years of experience under your belt, and why estimating is something that seniors are better at than juniors.
Even after 20 years you may never have hooked in new library X, but I'd be willing to bet you've done something kind-of similar, and your estimate will be more accurate than a person with 1 year of experience and has never done anything remotely similar.

Keep in mind you are not providing the estimate for the person who has done the task many times, you're providing the estimate to people who have never done it before. So for them, it absolutely is not trivial.
