Missing function postEphemeral in the service.

[tranhanam19999]

Hi everyone,
Currently, we're using the nest-slack: ^2.0.0.
Which is lacking of the API postEphemeral from slack.
Can you guys help me exposing this function?
For those who is facing the same problem with me, I have a solution which is.
We can make it any to use the client not being exposed like this:

(this.service as any).client.chat.postEphemeral({
      channel: 'some-channel',
      text: 'Hello, I'm only visible to you',
      user: theRequestedUserId,
});
