What are the secret achievements in The great Tournament 2? (SPOILER ALERT)

I’ve completed all scenarios being a prince, a lord, and being my MC’s son. But how do I achieve those secret achievements? I never achieved one in the game. Please help me. I already achieve all secret achievements in the First The great Tournament game and I don’t wan’t to break my record and just so you know the 2 secret achievements in the first game is The royal kazoo player achievement and Save Sir Robert.

You can see all of them here (secret ones are the ones that say hidden below them)
