Body

I'm deploying a GitHub Pages site with private visibility using a private repository within an organization. The content includes pages generated with Jekyll and OpenAPI specifications. The security is fine as only users within the GitHub Organization can access it.

However, when I post the link in our internal Slack, the OGP that appears includes the GitHub logo and the description: "GitHub is where people build software. More than 100 million people use GitHub to discover, fork, and contribute to over 420 million projects."

Is there any way to remove or adjust this?
