I wanna give a hint when trying to open inventory

[Neelke]

Since my custom story is a trilogy, it could be very difficult getting all the items together. Then I came up with an idea to lose the items in a creative way (figured that out already). When items are lost, I want them to also temporarly lose their inventory at the moment too.

Now, I want it to give a message when trying to open inventory at this time. Just like when you don't have a lantern.

Anyone knows how to do this?

(sorry if im confusing you somehow)
