I can send the Quicksight reports to users via an email.
Is it possible to share reports to Slack channel?
Thank you in advance for your support.
Yes.
You may have already found this out, but with Slack's paid plans you can set up an e-mail address that sends directly into a Slack Channel.

You can then add the e-mail address to the Quicksight reporting, or forward it from one address, and send it to a dedicated channel in Slack.
