I'm using a Metro M0 express with Circuitpython 7.0.0 and when I try to run a simple code with import adafruit_fingerprint I get a ImportError: no module named 'ustruct'. While checking the code I saw that the fingerrprint lib try to import ustruct only if typing, busio or struct isn't present. By checking the default module of Circuitpython 7.0.0 I can confirm the absence of typing and ustruct.
Am I missing something?
