Notifications are failing because of Slack Rate Limit with no Workaround.

Orb version:

slack: circleci/slack@4.5.0

What happened:

CircleCI jobs are failing the Slack - Sending Notification step

CircleCI build: https://app.circleci.com/pipelines/github/Alkami/configuration-utility/14481/workflows/3b13f8db-c6e2-4ff6-841c-5f77e14e72ff/jobs/14291

Slack - Sending Notification
Posting Status
Checking For JQ + CURL: Debian
Sending to Slack Channel: mobile-status
Exited with code exit status 22

I'm seeing this message in our Slack channel as well:
Due to a high volume of activity, we are not displaying some messages sent by this application. • Details

Expected behavior:

Successfully send the message, maybe retry after a second or two?

Additional Information:

There is currently no workaround or this failure. Once the Rate Limit is hit all notifications fail.
We need a retry loop here with a parameter to set the number of retries... maybe default to 0
An onion to set the seconds-to-wait-between-retries as well would be nice.

There is a retry option now in version 5.1.0
