Hello!

I can’t get `sendAppInvitation` API to work. I’m following documentation:

```auto
await zoomSdk.callZoomApi("sendAppInvitation", {
  user_list: [... array of UUIDs],
});

```

I’ve double checked and I am using `participantUUID` property from attendees.

I get this error:

```auto
Error: Validation error, please check API parameters.{"warning":"parameter participantId is deprecated for method sendAppInvitation"}

```

with code `10002`.

I’m on `5.10.6` client on MacOS, using sdk version `0.14.0`.

Hello, I’ve reproduced this bug. Please use the integer participant id for now, we will fix the bug and use UUIDs in the future.
