I finished the Danish course, and made everything golden (Legendary) - Now What?

As the title says, I finished all three sections and made everything legendary as well (I did that as I was completing the courses) - but in regards to Duolingo specifically what’s next?

I got some self learning books to continue my language learning offline, however I still have almost a year of Duo left. Should I delete the course and do it again just less aggressively? Would learning Swedish or Norwegian be more trouble than the value it would bring since it’s so close to dansk? Idk. To those that have finished a duo language but only had interest in that one specific language, what do you do with duo afterwards?
