Hooks: slack_on_success and slack_on_failure fail silently to work

[tgardela]

Dagster version

1.7.6 and older 1.5.13

What's the issue?

Wanted to use dagster_slack.slack_on_success and dagster_slack.slack_on_failure hooks.
Implemented them as in:
https://docs.dagster.io/_apidocs/libraries/dagster-slack#dagster_slack.slack_on_success
And they just plainly DID not work.
While I had a working slack - dagster integration I knew that was not the issue.
Finally I changed 1 line on both of hook's functions:
Changed from:
context.resources.slack.chat_postMessage(channel=channel, text=text)
To:
context.resources.slack.get_client().chat_postMessage(channel=channel, text=text)
And the hooks started working properly

What did you expect to happen?

The hooks to work

How to reproduce?

https://docs.dagster.io/_apidocs/libraries/dagster-slack#dagster_slack.slack_on_success
