How to use the mkmsdk.MKMOAuth1.MKMOAuth1.decode_signature function in mkmsdk

def test_header_signature_is_correctly_decoded():
    """
    Verifies oauth_signature is decoded correctly.
    This is done so the backend accepts the Authorization header.
    """
    given_header = {"Authorization": b'oauth_signature="test%20signature"'}
    expected_signature = 'oauth_signature="test signature"'

    decoded_signature = MKMOAuth1.decode_signature(given_header)

    assert decoded_signature == expected_signature
