Widget - Interact with object and a text box appears

Hello
The technical side of things is my biggest weakness!
I’m trying to figure out some basic BP so I can complete a simple project. I have followed several tutorials, but none seem to give me the result that I’m looking for.

All I want to do is have my character (3rd person mode) interact with an object and a box will come up with a few lines of text, the player is able to close the box after by input of the same interaction button.
I also want to play a sound when this interaction starts (e.g a voice actor reading the text) This isn’t compulsory, I could use more help with the other part of the question

I’ll have several items in the scene that will have the same interactive function. I apologise in advance for my lack of knowledge. Any help is welcome!
