AFAIC this issue is not solved. It's a workaround and we still need to put our heads together and trace the source. Why does it work for others but not PCC?
With the greatest respect, I beg to differ

After having a nights sleep and coming back to this, I have now taken notice of what the
NOTE says in the
Launcher Matching Rules section of the configuration. Additionally, clicking on the
More information link pops up a bit of technical info but it says nothing about how to actually implement a rule(s). Thanks to your discovery yesterday, we now have this working and I would dare to say that this is how things are supposed to work in this particular instance.
