Software version 19.30, which CIQ version does that imply?

For users its not always easy to find the CIQ version. Today someone send me that he had software version 19.3 on a fenix 5x pro.

I would expect that with this number i could find out myself which CIQ version is part of that. But apparently I can’t. Is there a relation between Software version and CIQ version or does this relation not exist? If it exist where can I find the details?
