This photo,

suggests, to me at least, that the phone can be charged while the keyboard, mouse and flash store are used.  True?

There are altogether too many unknowns here.  Looking at the date
of the photo - 2015 - some phones of that era could support USB
OTG but were unable to supply power to connected peripherals,
meaning you would need a Y cable to supply that separately.  Others
could do the job inclusive of power delivery, others couldn't work
in OTG mode at all.  Generally you couldn't use OTG and charge
simultaneously, it's a role reversal that early USB wasn't designed
for.
Things are different with USB-C but of course that is much later.
