To make in an air fryer: Prepare the dough according to the recipe. After the 10-minute rest (step 2), divide the dough into 4 equal pieces (about 230g each) and shape into loose balls. Work with one piece of dough at a time; transfer the remaining 3 rounds to their own greased containers, cover, and refrigerate for up to 48 hours. To bake, coat a 6" round cake pan with nonstick spray, then pour in 1 tablespoon olive oil. Add the dough round and turn to coat in oil. Cover and let rise for 30 minutes (or 60 minutes if refrigerated). Pour 1 tablespoon of olive oil over the surface of the dough, sprinkle with about 1/4 of the seasoning packet, then gently press your fingers into the dough to create dimples. Use the bake setting of your air fryer to bake at 300°F for 20 minutes for a soft, chewy focaccia, or up to 30 minutes for a crisper result. Turn the focaccia out of pan and let cool completely before slicing.
