You can either use a stand mixer with a dough attachment or with your hands. Add flour, salt, sugar and yeast. Mix well. Now add oil and milk to knead the dough until it becomes soft and smooth.
Proof the dough in the Instant Pot. Place the greased dough in the pot. Cover with a wet cloth. Place a lid on the pot. Set the Instant Pot to Yogurt mode on Normal Heat for an hour.
