Bag of bells

This bag appears made from leather, and appears to have three golden bells inside the bag. both the bag and the bells are marked with strange runes                                                                      the first bell has green runes the second bell has red runes and the third bell has purple runes

You can take a Magic action to pull out one bell from the bag and ring it the bell can be heard up to 60 feet away. When you take the Magic to pull out one of the bells you can chose one of three choices

1.[if you ring the green bell it reveals any hidden doors or chests within 30 feet]  2.[if you ring the red bell it reveals any hidden traps within 30 feet] 3.[if you ring the purple bell it reveals any invisible creatures within 30 feet] if a spell of 5th level or higher is being used to hide anything in rage it stays hidden

Notes: Spend a long rest concentrating and focusing entirely on it.
