Auth0 - python and PKCE token

Hi. I try to implement auth0 for my app in Flutter and API in Python. I would like to send a token for my API in Python and recognize the user.

Authorization on front side (mobile app) is ok, but on backend (python) something is wrong. Token is correctly when I check it on site.

This is a short video with my problem:

(I change my account data when I find a solution)

auth0.v3.exceptions.TokenValidationError: Authorized Party (azp) claim mismatch in the ID token;
