A kids book about becoming a spy/secret agent

I read this back in 2017-2019 and loved it so much. It was telling you to keep the book secret and potentially hide it. It wasn't a story, more like a manual on "how to be spy" There were challenges such as "learning how to use the washing machine" or "listening to an old person's past" when you completed the challenges you won stamps. There was a card in the book with blank cirlcles and you marked the circles as you won stamps. By the end of the book you counted your stamps and it told you what kind of spy youw ere or how successfully you finished the book. Basically teaching you how to do chores in a curious and fun way. The version i read had a blue cover (and blue caricatures inside). I TRULY can't remember the name of the book 😭 does anybody have an idea?
