Technically, you can't really hide apps using the stock OnePlus launcher on the OnePlus 5. You can either install a 3rd party launcher (like Nova Launcher) which has this functionality, or you can the app icon and name in the event you want to make it more inconspicuous. Here's how you can do that last part:
- Open the app drawer
- Long press the desired app icon
- Drag the app icon to the top corner of the display and release over over Edit
- Change the name (label) of the app, or tap the icon to choose from a list of currently installed icon packs (you can find them in the Google Play Store)
