     * discarded. Currently, the limit is 30 commands per 30 seconds, although this may not be fully accurate, and it's not possible to know the
     * exact limit.

     * @throws {AppletCommandError} If the command type is longer then 100 characters limit.
     * @throws {AppletCommandError} If the command is not an object or is missing required properties.
