Pat the chicken thighs dry with paper towels. In a large bowl, coat the chicken with oil and seasonings, then toss with cornstarch until evenly coated.
1 - 1½ pounds chicken thighs boneless skinless, ½ teaspoon kosher salt, ¼ teaspoon black pepper, ½ teaspoon garlic powder, 2 tablespoons corn starch, 2 teaspoon vegetable oil
Spray the air fryer basket with oil and preheat the air fryer to 400°F (205°C).
Arrange the chicken in a single layer in the air fryer basket and cook for 6 minutes. Turn the pieces and cook for an additional 5-6 minutes, or until crispy. You may need to work in batches.
Optional: For extra crispy chicken, transfer the cooked chicken to a plate or cooling rack and let it cool for 5 minutes. After cooling, spray the chicken lightly with oil and return it to the air fryer in a single layer. Cook for an additional 5 minutes.
While the chicken is cooking, prepare the sauce. In a small saucepan, melt butter and sauté garlic and grated ginger for 30 seconds until fragrant. Add sugar and honey, and cook for 1 minute. Then, add the remaining sauce ingredients and bring to a gentle boil over medium heat. Remove from heat.

Once the chicken is done, toss it with the prepared sauce.
Serve the chicken garnished with sesame seeds, scallions, and lime wedges.
