Color-Temperature is a GEGL operation and not scriptable.
You could try a third party script/plug-in that will show up in the Gimp pdb. Ofnuts once suggested http://luca.dealfaro.org/photography/Colortemp with the caveat that it is old and might produce unpredictable results with Gimp 2.10
An alternative, the gmic plugin, see http://www.gmic.eu has filters for both lightness and color temperature but not exactly the same as Gimp. Not difficult to script. Attached an example, lightens and adjusts color-temp. You do need gmic_gimp_qt installed, the example script entry shows up bottom of Filters menu.
