  crossorigin="anonymous"
></script>

Expected Result

The functions makeFetchTransport and makeMultiplexedTransport are available in the imported bundle, such as when using the npm package:

Actual Result

The functions are not available:

There's unfortunately a big disadvantage to adding these exports to the CDN bundles: The majority of our user base would be "punished" with increased bundle size for APIs they don't use.

That being said, there's a community PR that addresses this: #14925

I'll bring this up within our team to see if we can resolve this somehow.

makeFetchTransport should be available though:

We decided to expose makeMultiplexedTransport as an addon CDN bundle that users can add in addition to the SDK CDN bundle. Opened #15043. I'll update docs to show how to use the bundle.
