Google's file picker should be able to list any application on the device that supports being used to pick a file. What you need to do is tap the three lines icon at the top left (often called a hamburger icon), then you should see File Manager + listed on the left side if it supports being used to select a file. If it does not, then my suggestion for that app was a poor one and we will need to find a different app that works for that.
