How do I delete series on With the profile of. Continue watching?

I have been wondering for a long time how I can remove the series or films from "With the profile of… Continue watching" because a lot has accumulated there, especially because I'm watching my brother Netflix's account. Do I have to do this somehow in the settings or do you have an answer?

What series did you watch that your brother shouldn't see? XD

No, we mostly watch series together, but it's pretty annoying and confusing
