Optimization suggestion: Button for room code is preselected
Issue
During the test of all three subjects, it turned out that the room code was confused with the title of the event and/or it was not realized that this was generated automatically. The reason for this seems to be the intuitive assumption that the text box belongs to the room code.
Because the room code is preselected, the users are not aware of this afterwards and do not set it themselves, even if they would have made this decision later. At the same time, this fails to understand and "overlooks" the relevance and purpose of the room codes.
Suggestion
Accordingly, the room code button should not be pre-selected to be consciously selected by the user, so that the user has to deal with the room code decision beforehand.
