That hub doesn't work that way. The hub has a bunch of female ports, and one male USB C port. The male USB port is the only one that provides USB PD charging output, and it is also the only port that can be used with a USB host machine. This means that it cannot be used to change settings on the iFixit iron with a computer and give give the iron enough power to heat up. It's not an improvement at all over a regular computer that also cannot do both of these things concurrently. It looks like a lovely hub to keep on a desk for plugging in a laptop, but it is broadly limited to doing exactly that.
