Returning to game: how do you know youre on a sidequest

Possible spoilers.

For example the Lakna Rokee shrine.

How do I know if im on the side quests to unlock the shrine? If you play blind how do you guys know to complete the 3 pre-req quests to be able to start the shrine quest?

What do you guys look for to know this is an unlockable shrine when playing blind and for the first time? This goes for all other hidden quests and also hard to find korok seeds.

I only ask because I am returning to game and want tips on how to find things myself without guides.

Thank you.

Any other blind playthrough non spoiler tips appreciated as well!
