Press the extra firm tofu for at least 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a large bowl, toss the tofu cubes with cornstarch, sea salt, and black pepper until evenly coated.
Arrange the tofu in a single layer in the air fryer basket and cook at 400°F for 15-18 minutes, shaking halfway through, until golden and crispy.
While the tofu cooks, whisk together the tamari, maple syrup, chili garlic sauce, rice vinegar, grated ginger, minced garlic, and toasted sesame oil in a small saucepan.
Simmer the sauce over medium-low heat for 2-3 minutes until slightly thickened.
Steam the shelled edamame in a small amount of water or in the microwave until tender.
Transfer the crispy tofu and steamed edamame to a bowl, pour the warm glaze over the top, and toss gently to coat before serving.
