I have a simple async server page which fetches data on every url query change. This should trigger the Suspense fallback everytime a user modifies its search. On vercel and on localhost, this works as intended, and the suspense is shown on every query. However, with SST on Cloudfront it seems like the data is sent as a whole instead of streaming, so it makes it that the suspense fallback is never shown.

I created a simple reproduction code here:
https://github.com/Dragosp33/suspense-nextjs

and here are the 2 deployments:
AWS: https://d306s6ilnbid27.cloudfront.net/
Vercel: https://suspense-nextjs.vercel.app/

Does anybody know how to enable the streaming / suspense on Cloudfront?
I tried using the X-Accel-Buffering: no but cloudfront doesn't allow this header to be set. This was my best guess as I saw that the vercel request had this header and the cloudfront one did not.
