Custom send-event is not being in OwnCapabilities

[Vondry]

Which package/packages do you use?

• @stream-io/video-react-sdk
• @stream-io/video-react-native-sdk
• @stream-io/video-client

Describe the bug

1. When sending custom event I had to setup send-event call type grant, which i did not find documented either in https://getstream.io/video/docs/react/guides/custom-events/ or https://getstream.io/video/docs/react/advanced/events/
2. But the bug I see is that i do not see this in capabilities on the client, nor there is custom capability that i can check, if user can send custom events

To Reproduce
Steps to reproduce the behavior:

If you for example invoke this custom event warnUser for warning users, you need to have send-event as a setup grant.

import type { Call, UserResponse } from '@stream-io/video-react-sdk';

type WarnUserEvent = {
  type: 'warning';
  warn_by_user: Pick<UserResponse, 'name' | 'id'>;
  user: Pick<UserResponse, 'name' | 'id'>;
};

export const useCallWarning = (call: Call) => {
  const warnUser = (
    issuer: WarnUserEvent['warn_by_user'],
    user: WarnUserEvent['user'],
  ) =>
    call.sendCustomEvent({
      type: 'warning',
      warn_by_user: issuer,
      user,
    } satisfies WarnUserEvent);

  const onWarn = (event: WarnUserEvent) => {
    console.log('onWarn', event);
  };

  const isWarnEvent = (event: Record<string, any>): event is WarnUserEvent =>
    event.type === 'warning';

  return { warnUser, onWarn, isWarnEvent };
};

And if i filter later in my component:

  const { useOwnCapabilities } = useCallStateHooks();
  const capabilities = useOwnCapabilities();
  const canSendCustomEvent = capabilities?.includes('send-event');

I do not see send-event in capabilities althought the code works and events are being sent and received.

Expected behavior
I would expect:

1. send-event to be in capabilities list
2. send-event capability would be available on OwnCapability object eg. OwnCapability.SEND_EVENT

Screenshots
If applicable, add screenshots to help explain your problem.

Hi @Vondry, thanks for reporting this. Let me check with our backend team on why they don't include every possible capability in the own_capabilities list.
I'll get back to you.

Hi @Vondry, I've received a response from our backend team. The list of own_capabilities is arbitrary, based on common UI facing capabilities.
Unfortunately, send-event isn't there, and similar to the other issue you reported #1988, I'd recommend using roles instead.

Hi @oliverlaz, thanks for getting back. But the fact that the send-event is not there is rather bug than feature, because other similar events are being listed properly.

Should not this be taken into account and fixed? I have no idea about the codebase but from the developer perspective it behaves exactly same as other capabilities, so i would assume that it would not be rocket science to properly add it to the list (and document in docs).
