        This function retrieves the active camera operation from the current

        adds it to a specified group. The empty object is named based on the
        operation's name and the current count of objects in the group. The size
        of the empty object is set to a predefined value for visibility.

        Args:
            context: The context in which the operation is executed.

        Returns:
            dict: A dictionary indicating the operation's completion status,
