Ability to Choose Apps to Select Images for Upload

Up until the most recent update when I chose an external app to choose images for upload on Discord, I was able to pick which image viewer app I wanted to browse my galleries with. I used to be able to browse with the default Samsung Galley app, but now I'm forced to use the default whatever it is that's just a white background and has Google Drive icons without any option to pick my image app of preference. This "app" is really difficult and clunky to use to find the images I want to upload, when my Default Samsung Gallery app worked I had no problem doing that. Now I'm left with no options at all.
