hello all,
I have a problem when using 'import hmac' and I try to use it on my esp32

• before using it, I install it and it installs correctly, the code is the following:
  import upip
  upip.install ("hmac")

• the code is the following to use hmac:
  digest = hmac.new (s.decode ("base64"), a, hashlib.sha3_256) .digest ()

• the error that prints to me on my console:
  Traceback (most recent call last):
     File "", line 1, in
  AttributeError: 'module' object has no attribute 'new'

How can I use the new or remove this error?
I would appreciate the help
