[Custom Feature Question] Questing System

[SalyaDarken]

okay I'm trying to add quests to my game so if players wish to find notes by the passed away father that leads the player to two legendaries.
Other then that, I also want to add some short fun quests for players to get money or items.

Here is what I need from it:

• Simple to set up.
• Workings with PE 21.1
• Quests can be found and completed without talking to anyone. Like player gets the note quest line from picking and reading one of the first notes that they found.
• Easy to use in game.

I tried Modern Quest System + UI but can't fully understand it.
