Gt arcade pb to attach picture to a message

Hi, for the past few days, I've been having some difficulties attaching a picture or a document to a message on the GT Arcade app. I uninstalled and reinstalled the app, but nothing changed. It still doesn't work. It seems that I may have accidentally refused a permission when I was trying to add a picture, and now I can't add pictures anymore. When I click on the button, nothing happens, but I can still add image or video URLs.
