It's the dumbest setup possible with how android handles saved files, and even worse by all the hoops to put files or look at files from specific folders on your phone due to all the permissions crap.
But the easiest way to find where something was saved is to open up "Files" which is "Files by Google" to be exact. It will whatever file you saved or modified right there in the "recent" section at the top so you can look at whatever goofball place it was actually saved to.
Actually....android has the exact same app name. "Files" but I guess it's real name if you want to make sure you're getting the right one is "Files by Google"
For android, it seems to be the best one for finding recent stuff and navigating around. Like any newly downloaded or modified thing saved to the phone shows up under a "recently" section in Files, so it works out well for dealing with such a screwball android filing system.
