Upload to storage bucket directly (bypass webserver)

[adiba]

I get an error "Your request was too large to submit successfully" because Google App Engine & Cloud Run do not allow requests bigger than 32MB. So I would have to either upload the file to my storage bucket directly while still submitting file information to payload, thus making two requests, or perform a streamed upload or use Transfer-Encoding: chunked.

Is this currently supported? If not, can I write a plugin that does these requests?
