Question about Godox System Flash Adapter Bowens Mount

We have a new S2 adapter in our range, which can be used with the V1: Godox S2 System Flash Adapter Bowens Mount

The V1 is too thick because of the large round flash head. I just tried it. You can't clamp it. The adapter is made for the flashes with smaller heads.

Yes, that's what the adapter is for. I bought it for the central alignment of the system flash. What kind of connection does the softbox have?
