https://github.com/Azure-Samples/aoai-realtime-audio-sdk/tree/main/javascript/samples/web do not support ios?!

When I publish a static website to Azure cloud, the Android system can run it, but the Apple iOS browser cannot run successful.

at last, I found this code will not run well on apple device ios system, but android or windows are all ok:
main.ts file:
await realtimeStreaming.send(createConfigMessage());
why?
