Launch button not displaying

[ria-rivera]

Hello. I am having trouble making the launch buttons appear on my ipynb pages. I already configured the _config.yml file to include the GitHub repo, Binder URL, and enabled Thebe, but the launch button isn't showing up. Any suggestions on how I can troubleshoot the issue?

My repo is currently set to private but I've already tried it with a public repo and I had the same problem. TIA!
