Awesome! Keep me updated, it's quite unnerving when it happens. My daughters shot the Concept Lite down to 120 bar and the first time it happened I was like... uh...?
If you do need to get the valve out the part you're looking for is known as a "pin wrench/spanner".
No idea if it's 4mm, 3mm, 5mm, etc. I've never measured the ID of it.

Dunno if that helps and good luck!
Apparently this happens enough that Brocock now supplies a dedicated tool to remove the fill valve (see pic below). I can get the fill valve itself out using this tool very easily...the problem is, unlike on your Commander the other end of the fill valve is very firmly attached to a round extension piece that prevents you from accessing the other end of the fill valve to get to the o-ring. Since this extension piece is round, its nearly impossible to get a grip on it to secure it enough so that I can unscrew the fill valve to expose the other end it of. Thats why others have said they have to make contraptions out of wood, leather and other things just to get a grip on it.
You can see from the light scrape marks on the dark extension piece below the fill valve that it had been worked on before (it came to me like this, I did not mark those marks today). Really frustrating design.
