Linking directly doesn't seem to work either.

You've posted pictures of your DS crank and the bottom bracket shell. The bottom bracket is inside the shell. To see the external ends of the bottom bracket cups and spindle - which is necessary to determine what tool is required for bottom bracket removal - you'll need to remove the cranks. Removing just the crank bolts will expose the end of the spindle and might allow identification of the type of crank-spindle interface (square/ISIS/Octalink/other).
To remove the cranks after removing the crank bolts, you'll need a crank puller. However, see the important caveat about crank pullers below.
The crank is marked "Power Drive" and appears to be a FSA Vero crank. I
think that means it uses a FSA Power Drive bottom bracket - which has a splined interface to the cranks vice square taper or Octalink splined. I'm not terribly familiar with them; I believe the spline pattern
may have been FSA proprietary, but I'm not certain. I also think (but am also not certain) that type of BB uses the same type of bottom bracket removal tool as Shimano cartridge bottom brackets.
However, I'm not sure whether it requires a crank puller that's compatible with square taper or ISIS/Octalink splined cranks. Perhaps someone here has more knowledge about the Power Drive bottom bracket than I do and can assist further.
I could also be wrong about all of the above. With the crank bolts and cranks in place, we really can't tell much more.
If the crankset is marked with a model number somewhere, you might be able to work backwards from that and determine what type of bottom bracket it uses with certainty. The "Power Drive" marking is highly suggestive, but may not necessarily be definitive. Unfortunately, some versions of the Vero crankset were also made with square taper spindle interface (and may also have been made with ISIS spindle interface).
IF (and that's a big if) the bottom bracket is indeed an FSA Power Drive bottom bracket, you may find the info at this link useful. (The procedure is generally applicable to other types of cartridge-type bottom brackets as well.)
