But unfortunately, even when copying this. This DNG can be opened by Adobe's DNG_Profile_Editor_win_1_0_4.exe, and the latter can detect the Colorchecker and output a.

If you are willing to get your hands a bit greasy and don't mind coding, you can try Colour - Checker Detection, this notebook has an example on how to perform the colour correction. The explanation as to why is beyond the scope of this answer but beside proper lighting and geometry of the colour checker in your scene, you have to consider Metamerism. As a result, and once the matrix applied, the colour checker will effectively look better but your object colour might be worse. The matrix you generate will attempt to match the colour checker colours for your particular illumination conditions but those are entirely different than that used to measure the reference colour checker values. It is very tempting to use is systematically for colour correction but you will most likely generate a correction matrix that is worse than those the camera vendor or Adobe provides. Generally speaking, however, you should only really use the colour checker for white balancing and exposure correction. The lighting should be as uniform as possible and representative of the illumination conditions of your subject. Your colour checker is incorrectly lit and placed here.
