I'm curious how this is meant to be solved with RR? As far as I can tell, none of the submit hooks allow custom headers to be set.
#CloudFront OAC to lambda URL requires special header for POST - but none of RR's submits allow this?

By adding x-amz-content-sha256 of the payload in the header. But for a public accessible URL, that's not required:
Never sign origin requests
...
To use this setting, the Lambda function URL must be publicly accessible. If you use this setting with a Lambda function URL that's not publicly accessible, CloudFront can't access the origin.

But I wanted them to be signed...

The docs say to calculate the hash of the payload and put the x-amz-content-sha256 in the request header.

Yes? But it seems none of RR's submit hooks have a way of setting headers?
