In a large bowl, whisk together the flours, arrowroot, psyllium husk, and salt. Make a well in the center of the bowl and add the yeast mixture and oil. Using a dough hook on an electric mixer or a paddle attachment on a stand mixer, mix the dough until smooth. Dough should be able to hold its form but be sticky to the touch. If the dough is too sticky and not able to hold its form, add more chickpea flour 1 tablespoon at a time until the dough is firmer. Cover the dough in the bowl loosely with plastic wrap and allow dough to rise in a warm place for 30 to 45 minutes, until roughly doubled in size.
