[SPOILERS] MAJOR STORY SPOILERS so after you complete the game what do you do?

so the final cutscene where zelda and link are going to go to zoras domain and begin restoring hyrule played and i was so hyped and thought we would have a post game where we did things to eventually restore the castle but then it put me back to the title screen and my save in front of calamity ganon.

so my question is, is there no post game quest do i just collect all the items and do the shrines?
