By reducing the AOA actually, which happens as a consequence of
increasing airspeed. But see below also.

No. Increased airspeed happens as a result of reduced angle of attack, not
the other way around. Airspeed has no direct effect on AOA, though it does
have indirect effects (since changes in airspeed affect what AOA you need
for a given performance goal, whether that's turning, climbing, descending,
or whatever).

And it is interesting how that actually happens. The vertical component
of thrust takes a bit of the load off the wings which helps reduce the
AOA and keep it under the limit of the stall. Part of the weight is
in fact hanging by the propeller, like a helicopter.

Thrust does contribute, yes. But the primary reason for requiring
additional power is that, while the wing is capable of generating the
necessary thrust at a lower airspeed, higher angle of attack (all the way up
to the stalling AOA of course), the higher angle of attack results in higher
drag, requiring higher thrust.
