any idea to open a folder from android?

greetings to all. I have managed to save screen print from the game to a directory inside the save folder of the project. Now I would like to be able to open this folder by pressing a button. I use blueprints.

do you have any idea how to do it?

I have tried to access through the “open URL” node but it has not been possible.

it is android project and i use UE4.

Cheers
