Does nextauth set code_verifier cookie by default?

[twt-dev]

• Have setup authentik with below config

   ({
      id: "authentik",
      name: "Authentik",
      type: "oauth",
      version: "2.0",
      clientId: process.env.AUTHENTIK_CLIENT_ID,
      clientSecret: process.env.AUTHENTIK_CLIENT_SECRET,
      authorization: {
        url: process.env.AUTHENTIK_AUTH_URL,
        params: {
          redirect_uri: process.env.AUTHENTIK_REDIRECT_URI,
          scope: "openid profile email",          
        },
      },
      tokenUrl: process.env.AUTHENTIK_TOKEN_URL,
      userinfo: {
        url: process.env.AUTHENTIK_USER_INFO_URL,
      },
      profile(profile: User) {
        return {
          id: profile.id,
          name: profile.name,
          email: profile.email,
          team: profile.team,
        };
      },
    }) as OAuthConfig<User>

• user is redirected to the authentik login page

• on logging in, following error comes up:

  error: [Error [OAuthCallbackError]: token_endpoint must be configured on the issuer] {
  code: undefined
  },
  providerId: 'authentik',
  message: 'token_endpoint must be configured on the issuer'
  }

On digging in, I figured, code_verifier is not being set in the cookie. Is it something that nextjs does by default? or do we need to write the logic to set this code.
