AWS WebGL Securly Get Images?

So AWS SDK is not compatable with WebGL.

Is there any way to securly pull images from an S3 bucket?

Myabe using the http get to authenticate with cognito then pull the images?

Any suggesstions would be very helpful, I just need some way of getting images securly from an S3 bucket on a Unity WebGL project.

very curious if you found a solution to this. I’m building cross-platform using AWS Cognito for authentication, but for Unity WebGL I’m exploring a solution.
