Create Browser Extension -- 2

WE are seeking Freelancers that have extensive experience writing Browser extensions and Browser's Background Worker processes. This project is only a very preliminary qualification to move on to the main project.

(The main project will be to create a full featured SIP Soft Phone Browser Extension. We already have a web-based React-Phone [Inbound, Outbound, Hold, Mute] working. We'll share the code for you to build on. But this is another project. You must complete this project to get the opportunity to work on the SIP phone extension)

This Small Project we would like you to complete a simple task (1-2 hours)

Basic Info:

-> We already have our backend with OAuth 2.0 support,
we'll create a "Proof Key for Code Exchange (PKCE)" OAuth client for you.

Your Tasks:
-> You have to use the PKCE Client to authenticate the extension
-> Store the token securely, possibly refresh_token as well,
So, the user doesn't have to login again and again.
-> To show-case the login functionality works,
Show the Logged in user's name on the extension.

You will make delivery to private github we will provide later.

Delivery needs to be within 48 hours. After 48 hours any open project will be canceled.
Project will be awarded to multiple Freelancers so you must provide separate proposal for us to award project.
