In the next section of the menu 
you can control the general settings of EngrApp:
- Mute all chats.
- Hide to all groups. Hiding here the eye will appear close, that will indicate that even though the setting of a particular group is visibility on, you will be hidden.
- The last general setting is the one you have to be more careful. If you activate it, anyone who invite you to a group will be able to see you. To activate this setting changes the setting to be by default hidden in any group that you make, you are invited to or you adhere to. Our advice is to have this one deactivated at anytime.
