i bought new link 4 port usb hub attach pi zero.

when opened realised there space inside hold pi.
have taken photo of circuit board:

can walk me through (small steps!) on how join 2 boards can power pi through hubs power supply , use usb ports on hub too?

reading documentation of usb hub chip can see em1 connections seem d+ , d- of upstream usb.
taking silkscreened em1 top: top trace d+ , bottom trace d-. solder jumper wire d+ pp22 , wire d- pp23 (test points on bottom of pi zero).
majority of board seems ground plane gnd should no problem.
i'd inclined try upper "f1" point +5v, after fuse...
