/**
 * Displays a login screen that users can interact with
 * using an ID card in their hand.
 * Special elements can be invoked by defining machineType prop
 * possible string arguments are defined in SpecialMachineInteraction in loginScreen.js
 *
 * Required data fields:
 * * `scan` — The name of the currently inserted ID
 * * `isAI` — Whether the user is an AI. If true, shows "Login as AI"
 * * `isRobot` — Whether the user is a robot. If true, shows "Login as Cyborg"
 *
 * Clicking the main button calls the `scan` TGUI act.
 * Clicking either the AI or normal login button calls
 * the `login` TGUI act with the a `login_type` parameter with the value:
 * * 1 (LOGIN_TYPE_NORMAL) if it's an ID login
 * * 2 (LOGIN_TYPE_AI) if it's an AI login
 * * 3 (LOGIN_TYPE_ROBOT) if it's a robot login
 *
 * You will have to handle the AI login case in the same action.
 * The normal login button is only available when `scan` is not null.
 * The AI and robot login buttons are only visible if the user is one
 * @param {object} _properties
 * @param {object} context
