Description

According to slack's doc:

If you exceed a rate limit when using any of our HTTP-based APIs (including Incoming Webhooks), Slack will return a HTTP 429 Too Many Requests error, and a Retry-After HTTP header containing the number of seconds until you can retry.

We should explore if we can honor the Retry-After seconds to perform the next poll.
