Search isn't working

[callmefredcom]

Nice project, I've implemented it for my site https://scrib.am which used to be on Super. Just one problem though: the Search isn't working (so I've hidden the search widget via css...). It can't communicate with Notion. I've noticed the same issue on this deployment: https://61ec3fa483f671464f0b44f4--amazing-chandrasekhar-c12ace.netlify.app/ Impossible to use Search. At first I thought it was caused by cross-origin issues (before moving to my custom domain) but it's not the cause. Could you help debug this? Thanks.

Also: I would like to know how to add a custom menu to the header (if it's not too complex).
