Nextcloud Office's Follow-me slideshow

The feature in now available in Office: CollaboraOnline/online#13048 and it has been also documented in @lpranam 's blog:

The use case, for example, is a video meeting or a classroom with a teacher and students. The teacher starts a presentation, which gets auto-started for the students. The students' views update automatically as the teacher steps to the next slide. This is meant to work with any presentations that Impress can load, using the WebGL-based presentation output of Collabora Online.
