You would’ve gave little bit more details i guess. But anyway, check Blueprint tutorials first, it does not looks like you did.
i wanted to see the blueprint of how the first person example is but its not there when i see i click on blueprint, im very new to this and it must be one hidden button so help me out guys 
You can see the blueprints that exists, but since the game is written in c++ you’re not very likely to find that much info there
