Help with a Drupal module. Oauth 2.0 and OpenID connect using Drupal backend and React frontend -- 2

Job ID: 31490474

Budget: $30 – $250 USD

Version: Drupal 8
Module: https://www.drupal.org/project/simple_oauth

Issues:
Tokens that are expired are not deleted from database
Profile changes lead to token being revoked
Logout endpoint missing (?) or not found in documentation
Token endpoint not working without client secret

What we need:
A module that implements oauth2 protocol in a react context in a more efficient way without causing the issues mentioned above
Recommendations for react packages. Already tested and could use: https://www.npmjs.com/package/axios-oauth-client

The ideal candidate would either guide us to solve the issue or we could grant him/her access to check it out themselves if it's easier for them. You'll get paid as soon as our issue is solved. Please don't request funds for "reading documentation".

Note: We are open to suggestions regarding different ways of authentication if you have a better option to achieve our goal.

Thank you all in advance, any help is much appreciated.
