Remove the apps from the phone? Settings/Apps. Choose the app, force stop, clear cache, clear data, Uninstall.
Clear it from somewhere else? From where? (Finder is the MacOS file manager, you won't find it on an Android phone.)
From the apps that pop up when you want to run a file or share it? You have no control over what shows up, that's decided by the app's developer.
From tapping the Recents button? Tap the X at the upper right corner of the app. (But that list get rebuilt as you run different apps.)
