How to give other users access to the repository via Github API?

Question

I've got an software where single user can have many projects and can invite many members to single project. And right now I need to create an integration with Github API and connect single project to single repository in Github.

So, I'm starting with authorization to Github via Oauth. First step was adding in React app a single button with redirecting to this URL:

`https://github.com/login/oauth/authorize?client_id=${process.env.REACT_APP_GH_CLIENT_ID}&return_to=/login/oauth/authorize?client_id=${process.env.REACT_APP_GH_CLIENT_ID}&redirect_uri=${githubRedirectUrl}&scope=repo`

and handle callback from this authorization. After redirecting to set earlier callback url I gets an code and send him to server side, where later I make request to this endpoint

https://github.com/login/oauth/access_token

which return me access_token. This access token I save in database and use in every request to Github API via account which is connected.

And now is time, to integrate project with repository of the autorizated earlier account.

I create a simple list of all account repositories, and after click on one record I update project object with values like name, url etc.,

And right now is the most important question, how to enable other application users to perform operations on a connected repository? Should I save in project also access_token of the owner (which connect repo to app) and use this token in all requests to Github API?
