architecture enhanced
strong architecture with generic repository pattern

• create group endpoint, first user will be logged in user
• add users[] to group

Logic for adding user to group:-

• added user cannot be added to group
• filter out already present users from adding list, then add new users

• remove single user from group

Logic for removing user:-

• if only one user remains, and he removes himself, then delete entire conversation from db
