That's a highly relevant observation. Here's paragraph 46:
46 Other journalists, commentators and members of the public who are observing a hearing, whether in person or remotely, and who wish to use live, text based communications during the hearing, must apply to the Tribunal for permission. That application should be made in advance of the hearing if possible. If the application is made on the day, it should be made to the clerk and not directly to the Tribunal. The application will be considered by the Tribunal at the next appropriate point in proceedings and may be refused if the Tribunal considers that such live communication may interfere with the administration of justice. There may be a delay in permission being granted if the application is made during the hearing.
