md`... just realized I can't build this, because the next step in the GitHub flow requires me to POST my client_secret and I don't want to put that in a public notebook: https://docs.github.com/en/developers/apps/building-oauth-apps/authorizing-oauth-apps#2-users-are-redirected-back-to-your-site-by-github
Actually I'm going to try the device flow instead, since it looks like that doesn't require sending a client_secret https://docs.github.com/en/developers/apps/building-oauth-apps/authorizing-oauth-apps#device-flow`
