TeamViewer logfile: explanation of role numbers

Hi,

I am trying to understand the whole TeamViewer logfile and currently struggling a bit with these role numbers like "... participant was added with the role X", where X is a number between 0 and 7 (there may be more possibilities for X)

Is there an explanation guide for this numbers? My current guess is that 6 is for presenters, 7 for presenters with someone else controlling the computer, 3 for a usual viewer and 2 for a viewer controlling the presenters computer.

Is that correct? Has anybody more information about these numbers?

Thanks in advance for your help!
