Authorization code flow without access token

Which SDK: The latest auth0 react sdk

I am using the last auth0 react SDK that i install in my front (react js).
My problem is: I do not receive an access token in the end of authorisation code flow with PKCE, even if i am authenticated successfully.

I need this access token to pass it to my back end.

the last thing that i see in the workflow is the following request:
<redirect_uri>http://localhost:3000</redirect_uri>
<client_id>EctY…</client_id>
<code_verifier>umEinatHl8g3KvxuEjtQ…</code_verifier>
<grant_type>authorization_code</grant_type>
uVnt3apMUISvlQEg

I do not receive the response with access token.

What scope are you passing? What audience?
