I have not tested this outside of comparing the gcode between SuperSlicer and Cura. Values were within 1mm of of each corresponding value.
I don't know python and have no interest in learning it, hopefully someone can clean this up.
START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0} AREA_START_X=%MINX% AREA_START_Y=%MINY% AREA_END_X=%MAXX% AREA_END_Y=%MAXY%
Those are placeholder values from Cura, they will be replaced by the first layer temp for both the hotend and the bed. If this doesn't work then something is wrong with your Cura. I don't know if Philbaz's screenshot will help you because I don't believe I have the plugin for printer settings and I never ran into issues.
